HouseTech’s main successes have been in schools (private, state and boarding), and universities, 

The company is working with the Mayor of London’s RE-FIT programme for the UK, installing the products in UK schools nationwide.

We have interest free funding available for our product  and installation for schools and universities.


WOW.!! ..HouseTech and Vale of Glamorgan Council have been monitoring the controls at St Josephs Primary School in South Wales. The target set by the school and council  was a 20% decrease in gas usage over a 6 month period which equated to a  16000 kwh reduction. 

After just under 3 months HouseTech controls exceeded the savings target of 16000 kwh. November saw a 43.6% drop in kwh , December recorded a 35.8% drop and January  a 32.4% decrease. No other energy saving measures have been implemented at the school. 



HouseTech have recognised typical problems with heating schools and universities  as follows:

Heating unoccupied rooms

In many schools, classrooms are heated long after teachers have left just because admin staff stay longer in different parts of the school. Unless the teachers or the caretakers in these areas remember to turn the radiators down each night and up again in the morning there are many hours when empty classrooms are wastefully heated. Even if they did turn the radiators down each night they would then come into a cold room the next day!

Hot and cold rooms

There is generally an imbalance of heat (resulting in hot and cold areas) as people turn their individual rooms up to maximum, which results in other rooms getting less heat. Then the hotter rooms’ occupants will open the windows as their rooms become too hot, thus wasting costly heat to the outside. Also, because heat rises, top floors frequently have windows open to control temperatures.

Inaccessible radiators

In many instances the radiator controls are behind desks or low surface temperature radiator covers etc. so access to them is difficult and they remain in the same open position day after day. This results in the pin in the TRV (thermostatic radiator valve) becoming seized, so water does not flow correctly through the radiator. (The HouseHeat valve will fully clean the pin on the radiator valve once a week)

Often, in smaller buildings, there is one thermostat that shuts down the boiler when the set temperature is reached. This may mean that certain rooms have overheated and others have not got up to temperature.

Building Management System (BMS) problems

Even where there is a BMS in place, a whole building’s heating is on despite there being occupants in only a few rooms. This is because BMS does not allow for room-by-room control. A typical example of the shortfall of BMS systems is in halls of residence, where students may not occupy their bedrooms for days on end but the room is still being heated, often with windows open!


With HouseHeat, rooms can be programmed individually for time and temperature; so the temperature in classrooms is reduced automatically at the time that teachers leave but individual admin areas can remain heated for longer. The rooms will be programmed to turn up again in the morning. This means that staff do not have to walk around each room turning radiators up and down.

HouseHeat Thermostats can be set to a temperature of, say, 20 degrees and locked in that position. Our protective thermostat cover can be placed over the thermostat so that no one can interfere with the temperature or the times set. As it is screwed to the wall, it becomes largely theft proof as well as tamper proof. This results in constant room temperatures all over the building so no occupants can grab more heat for their room and there are no more hot and cold classrooms. There is no dial on our valve motor so it cannot be turned up. It is also secured in place by bolting it to the radiator with our lockable collar, which makes theft or tampering difficult.

HouseHeat thermostats are positioned in the middle of the room and do not measure the temperature at the radiator. They measure temperature where the occupants are. (This is crucial to heat saving and should not be underestimated)

This has two benefits. Firstly, because the thermostats are away from the radiator, they will detect rising heat from the floors below and solar gain from the outside (if in a south-facing room), and therefore automatically restrict the water flow through the radiators. This allows that water to just flow only along the pipe and not through the radiator, which means that water’s heat can be used elsewhere. Conversely, if they are in a north-facing room, perhaps on the ground floor, the thermostats will instruct the HouseHeat valve to automatically open the radiator to let in more heat to achieve the set temperature. Communication between the wall-mounted thermostat and valve motor is every two minutes as the valve is modulated in its opening. Secondly, as the thermostat is in the middle of the room, it is more accessible, so adjustments, if required, are much easier as furniture does not have to be moved out of the way.

As there is no single thermostat dictating temperature for the whole building all rooms will achieve their set temperature target as they each have their own thermostat controlling them.

A last optional addition to the HouseHeat system is the built in window sensor. If a window is opened the sensor will instruct the thermostat to turn the radiator down to a pre-selected temperature so that heat loss to the outside is restricted.

The final heating problem listed above refers to halls of residence and BMS systems not being clever enough to know if the room is occupied or not. So whole buildings can be heated even though only one or two rooms are occupied. With the HouseHeat Advanced Set there are 24 different time and temperature settings per day, so in halls of residence you can leave the thermostats unlocked but they will still be behind the protective cover. The fee-paying students can spin the temperature wheel up on the thermostat if they are there but, perhaps, every 3 hours, the thermostat can revert to a setback temperature of, for example, 17 degrees. If students are not in residence their rooms will stay at this lower temperature until they return and spin the temperature wheel up again. This takes any guesswork out of room occupation because if they are not being used they are not being heated!
