Reducing the bills in HMOs and Student Houses

Reducing the bills in HMOs and Student Houses

I often get asked the question from landlords; how do I reduce the heating bills in my HMO (House of Multiple Occupancy) but at the same time not alienate the tenants by them being too cold. The problem is that the tenants want to have control over the heating in their room (which is totally reasonable as they are paying good money to rent that room) but we all know that as the tenants are not paying the bills there is no real incentive to turn the heating down when they leave the room or go away during the holidays. Worst still the tenants can leave the window open when the heating is running if they are too hot!

The solution is to give the landlord control of the heating, but the tenants control of their room. To automatically turn down the room when it is not being used, and automatically shut off the radiators if a window is opened close to them.

Recently we installed the Genius Hub into a number of student houses for Student Cribs because they want to give their tenants premier comfort in their rooms but not have to keep the heating on 24/7 to achieve this

The problem with other systems they had tried in the past is they control the boiler on its own, and this means that money is continuously wasted heating unoccupied rooms. Also these systems often have to be manually triggered by the tenants in the house to boost the boiler, causing complaints from the tenants because they have to get up in the middle of the night to boost the heating, or it is cold in the mornings if they get up before it has been boosted by another member of the house.

Genius Hub solves these problems because it only heats the individual rooms with smart TRVs (Thermostatic Radiator Valves) which replace the existing TRVs. Occupancy detectors notice when the rooms are being used and when they are vacated, so the rooms automatically drop to a set back temperature when the room is left.

Carbon Trust state that for every 1ºC you drop in temperature you save 7% off the heating bill. The Genius Hub automatically drops the temperature by 4ºC in rooms when they are not being used saving 28% when the tenants are not there.

If you add this to not wasting heat with windows being left open and turning the heating down in the holidays the Genius Hub saves landlords more then 30% off their heating bills, and gives them peace of mind that in the spring they will not be stung with an enormous bill because the tenants left the heating on all winter.

Genius Hub is a Carbon Trust accredited product because of the savings that it generates. Student Cribs are using it to help deliver value to their tenants in affordable rent as well as premium comfort in their rooms.

Installation is fast and simple, a typical 6 bed property would take about 2-3 hours. The Genius Hub is installed next to the Internet router and the Genius Valves screw onto the radiator without the need for any re-plumbing. The occupancy sensors can be placed anywhere in the room where they can pick up the tenant in the room.

Student Cribs are benefiting from the savings and the tenants are benefiting from the better comfort when they are in the rooms, it really is a win-win solution.

Will Brexit affect your energy bills?

A ‘no deal’ Brexit will likely result in inflated energy bills for homeowners next winter, warn experts from smart central heating provider, Genius Hub.

According to Alasdair Woodbridge, CEO at Genius Hub, uncertainty surrounding the strength of the pound is just one of many reasons that could see some people struggle to keep their homes warm next winter.

Other factors, irrespective of currency fluctuations, include:

  • Increased transportation and importation costs, particularly for gas, as Britain imports more than half of its gas
  • Uncertainty around green energy initiative targets
  • Lack of investment in Britain’s energy infrastructure from the EU
  • Whether Britain will remain in the EU’s Emissions Trading Scheme after 2020

Energy industry experts have also suggested that Britain’s reliance and investment on pipelines between other countries could impact energy bills and the fight against climate change. The four cables connecting UK, France, Ireland and the Netherlands help to stabilise costs and guarantee energy supplies when wind and solar power is insufficient. A no deal Brexit could disrupt the free flow of energy, by imposing tariffs on the connectors.

Alasdair Woodbridge says:

“There is so much more to consider, in addition to the strength of the pound, that could negatively impact energy bills for homeowners, following a no deal Brexit.

The UK receives approximately €2.5 billion a year from the EU, in the form of energy grants and loans. If this funding is reduced or cut off entirely, the cost will undoubtedly be factored into consumers’ tariffs. Additionally, if the value of the pound falls, the cost of importing equipment and machinery to improve our infrastructure will also be affected. There are so many different facets to Brexit, a considerable increase in the cost of energy bills can’t be ruled out.

My concern is that the people who need it the most in the winter months may struggle to make ends meet. While for some, heating is more of a comfort factor, for the elderly or people with illnesses and disabilities, it can be crucial to their health.”

Genius Hub is urging those running on traditional central heating systems to upgrade to a smart central heating system before next winter. Smart central heating systems like Genius Hub allow homeowners to control the temperature of rooms on an individual basis, with their customers saving an average of 20%-30% on their energy bills annually.

The difference between Genius Hub & Nest or Hive

The question we often get asked is what is the difference between Genius Hub and Nest or Hive, now we know there is a huge difference it’s like comparing a model T-Ford car with a state of the art Ferrari.

But you don’t have to take our word for it you can see what others think. Long time customer of Genius Hub is Matt Egan, who also happens to be a technology journalists and works for publications such as Tech Advisor.

Well Matt has just reviewed our latest system and in the process upgraded his home system.

Genius is the smartest smart home heating system you can buy.

Here is how Matt describes the difference between Nest or Hive & the Genius Hub;

“As we have described, this is not a Nest, Tado, or a Hive – it is much more sophisticated, and somewhat more expensive than those products. Hive or Nest is, in essence, a dumb on-off switch that allows you to remotely switch on and off your heating. “

Read the Tech Advisor Review

"it is a great product, and if you are looking to install in your home a zoned smart heating system, we are happy to recommend Genius"

Feature Focus – Footprint mode

The Genius Hub footprint mode is where things get really smart. Footprint mode is unique to Genius Hub’s smart heating system and NOT available with simple Smart Thermostats like Nest or Hive.

Footprint mode uses the Genius Hub Room Sensors to learn the movements of people within the house, then predicts future usage and automatically controls your heating. 

If you don’t have any Room Sensors installed then you will not see any of the footprint options in the app (buy them in the shop to start using footprint mode). 

The Room Sensors also bring more Smarts to your heating, footprint mode consists of 2 main parts:

1. Reactive heating: This is when the Room Sensors trigger the heating due to occupancy being detected or no longer being detected in a room. If there are repeated triggers of occupancy in a room in footprint mode (such as a person starts using the room), the heating will be triggered on. If the system then stops detecting occupancy triggers the heating will be allowed to turn off and cool as the room is no longer being used.

2. Predictive heating: The other main part of footprint mode is that the system will use the occupancy triggers to learn when the system is normally used and schedule the future heating accordingly. A 7-day schedule is built based on the last 2 weeks occupancy, so if the room is repeatedly used at the same time the heating will be brought on for that time for the next week. As the schedule is based on the last 2 weeks, if your lifestyle changes the system may take up to 2 weeks to fully adapt to your new schedule. This can mean that if you do not use the room at the normal time, the heating will still be brought on at the start of the predicted schedule, but will turn off when no occupancy has been detected for the set duration.

Footprint modes

In footprint mode there are three modes you can set that determine how energy efficient you want your heating system to be. They are:

Comfort: The room will heat both reactively and predictively and pro-actively heat between usage gaps

Eco: The room will heat both reactively and predictively. 

Super-Eco: The room will only heat reactively. 

Like all Genius Hub features there is lots of flexibility and depth. If you want to learn more then see our footprint mode support document.

Boiler plus did you know?

Boilers last between 10 & 15 years and sometimes much longer, so you can be forgiven for not keeping up to date with the latest legislations around boilers. Something changed last year that may affect you next time you change your boiler, grab a cup of tea and we will explain.

New Legislation

From April 2018 the legislation around heating manufacture and installation in the UK changed, these changes were introduced by the Department for Business, Energy and Industrial Strategy (BEIS).

The most notable changes were:

– A minimum efficiency level for all boilers manufactured and installed was set
– Time and temperature controls required for all gas and oil boiler installations
– Combi boiler installations must also include one of the following: Weather compensation, Load compensation, Flue Gas Heat Recovery, Smart controls.

These are new Building Regulations so will be applied for all new builds and those developing properties or replacing a boiler. The legislation is designed to help the UK meet the carbon emissions targets by 2020.

Energy & Cost Savings

The Government document sets out a typical consumer’s costs and energy savings from Boiler plus in the first year of operation and is shown in the table below: 

Learning thermostats (smart control)

 Load compensation 

 Flue gas heat recovery

Weather compensation

Additional upfront costs (£)

190

50

460

130

Yearly bill saving (£)

17

4

15

4

Payback period (years)

11

13

14

35

The results show that learning thermostats which is included in a Genius Hub Smart heating system and load compensators pay back within a typical heating systems lifetime (15 years). 

Get ready

Further legislation is likely in this space to continue the drive for greater energy efficiency of UK households. You can get ahead of this by installing a Genius Hub Smart heating system which not only meets the current Boiler Plus legislation but takes you further and provides greater energy and costs savings.

Smart Electric One Bed Flat

I’m Simon, an engineer at Genius Hub and here’s how I installed a Genius Hub system in a one bedroom city centre flat.

Why Did I Want It?

A few reasons: 

  1. To get remote control of the heating. Now I can turn on the heating when I’m on the way back home, so that it’s warm when I arrive.
  2. To get better temperature control. The existing radiators do a good job of warming up the room, but usually it gets too hot, so there is a regular process of turning up or down the thermostat on the radiator, or just turning the radiator on or off.
  3. To be able to set up a schedule. Pre Genius Hub, it was fiddly to set a schedule, and it had to be done on each radiator individually, by pushing in pins, and was not possible at all on one of the radiators.

Setup & Kit

The property is a typical one bedroom flat in Birmingham City Centre. In addition to the bedroom (1 radiator), there is one bathroom (1 towel rail), one living room (two radiators), an entrance hall (no radiators), and a hot water tank.

I used the following Genius Hub kit:

  • 1x Genius Hub
  • 2x Room Sensors
  • 4x Electric Switches
  • 1x Hot water temperature controller
Genius Hub Electric Kit Unpacked

(Click below to buy the same items that are mentioned)

Install Process

The Genius Hub

The Hub was easy enough – it just plugs into the broadband router with a network cable, and into a wall socket for power.

Hub with Router

Room Sensors

Also very easy – they just stick to the wall with a sticky pad. One in the bedroom, and one in the living room.

Remember to remove the little black battery tab from the back of the sensor, before sticking it to the wall!

Electric Radiators

This is a bit more involved as it requires rewiring electrics.

Please note that I am a trained electrician, and you should not undertake any electrical work unless you are an ‘electrically competent person’.

The process involves removing the fused spur that is used to turn off power to the radiator, then fitting a ‘dual dry lining box‘ so that the electric switch can sit next to the fused spur.

In order to do this, the old single dry lining box needed to be removed, the hole in the wall enlarged, and the dry dry lining box fitted. See the attached video for this.

The towel rail is the same as the electric radiators.

Hot Water Tank

Hot Water Tank Controlled by an Electric Switch

Again, this required some rewiring, as the switch replaces the existing programmer.

In this case the switch was mounted to a ‘1 gang surface pattress box’, rather than embedded into the wall.

The electric switch was connected directly to the immersion heater, that heats up the hot water tank, as it can switch up to 3kW, which is the same rating as the immersion heater. 

Additionally, the temperature probe was inserted into the tank jacketing, and pressed against the side of the tank, to measure the water temperature.

Setting Up The System

The kit came with the devices already ‘paired’ to, and tested with the Genius Hub, so as soon as it was all powered on it was good to go.

Each device is labelled with a sticker that says which ‘zone’ it is assigned to, so as long as the device goes into the right room, everything will be fine.

The first time you use the app, you have to register it, choosing a username and password, and entering a postcode, so that the weather information for your area can be retrieved.

The install took approximately two and a half hours to complete.

 

In Summary...

It took me a couple of hours to install the kit – if you would like an engineer to install it, then ‘pro-install’ can be arranged (see this link).

Also in this particular property, all of the devices that were being controlled were electric radiators. Genius Hub can also be used to control traditional ‘wet radiators’ (central heating radiators) and underfloor heating too. Check out the website for more information on these.

Genius Hub Public API – Quick Start!

Get started using the Genius Hub API. This is the first post in a series about how to use the public API, step by step.

In this article, we are going to use NodeJS to see how we can access the API to extract some data from a Genius Hub, and display it to the user.

If you are familiar with using REST APIs, jump straight to the docs: https://my.geniushub.co.uk/#/docs otherwise, read on!

Intro – Tokens – why use them?

The API uses tokens. Why? They have the following advantages over a username / password authentication scheme:

  • They are more secure
    You do not have to pass around your username and password.
    They are by default as secure as a very long and complex password!
  • They expire
    You can make a short lived (temporary) token, and pass it to someone, if you so desire.
    Left your  username and password written down in your old notebook? If you did this with a token (or the electronic equivalent), then you know that the token will only exist for a sensible amount of time, and then expire.
  • They can be revoked
    Accidentally committed some code with your token in it? Easy to fix! Just revoke the token and create a new one.

So, we are going to use tokens to access the API. How do we do it?

Step 1 – Check that your Hub is up to date

Your Genius Hub needs to have have firmare version 5.2.10 or higher to allow access to the public API. You can check this by logging into the app (link) and checking the ‘About’ page. If your Genius Hub is on a lower firmware version, you will need to update it by choosing ‘Check for updates’.

Step 2 – Generate an API token

Visit https://my.geniushub.co.uk/ and log in with the credentials for your Genius Hub.

Select the ‘Tokens’ menu from the top of the page.

Click the yellow ( + ) icon at the top right of the page to create a new token.

Give the token a name. In this case call it something like ‘Genius Hub API  demo’.

You can leave the  expiration date as it is, or extend it if you prefer. The default is for it to expire in one month, which helps to keep your Genius Hub secure.

You can also provide a longer description for the purpose of the token, if you wish.

Press Create Token.

Step 3 – Access your token

Choose the ‘Tokens’ menu option (you will be taken here automatically after creating a new token).

Press the ‘Copy to clipboard’ icon to the right of the token that you wish to use.

Step 4 – Write some code!

The example below uses Codepen. You can edit the code directly to play with it.

Just set the ‘myToken’ variable to a token that you have generated, and you should find a list of your zones and their temperatures printed out in the ‘Result’ pane!

See the Pen Genius Hub Public API Demo by Simon Turner (@smturner) on CodePen.

So, what’s going on here?

ES6

The code above is using ES6 (‘modern Javascript’). Here are a couple of great resources, if you want to learn more:

You don’t have to use ES6 / Javascript! Pretty much every programming language has a way to make HTTP requests. Above is just a quick and easy example of how to get started.

Get the data

The ‘getGeniusHubZoneData’ uses ‘fetch’ which is an API call that is built into most modern web browsers. It lets you make an HTTP request (in this case from my.geniushub.co.uk), and capture the result.

It uses the ES6 version of promises (async / await) which basically means that the code will wait whilst the browser goes away, talks to the remote server, and collects the result.

We are setting the Authorization header, to tell ‘fetch’ to use our token, so that my.geniushub.co.uk will know which Hub to get the information from, and also authenticate that we are allowed to do that!

Finally, the API returns results in the JSON format, so we call ‘data.json()’ to convert the HTTP body text, into a javascript object that we can use directly in our program.

Show the data

We’ve called the getGeniusHubZoneData function, now let’s put the result where we can see it.

The API endpoint that we called ‘/zones/’ returns a list, so we’ll print that to the screen.

We use the ‘document.write’ function to put HTML onto the webpage output pane.

We iterate through each zone one at a time, using a ‘for’ loop, and for each zone, we print out the information that we want: zone ID, zone name and zone temperature (if the zone a temperature reading).

Discuss!

Let us, and other users know what you’ve been up to on our forum: https://forum.geniushub.co.uk
