To control your heating, the Drayton Wiser system has a wireless heating relay that connects to your boiler to turn it on and off. There are two versions of the kit available. The first has a single-channel control that’s designed for combi boilers, turning the heating on and off only. In addition, each room can have Open Window Detection turned on. This uses an algorithm to detect when a draft is detected, suggesting an open window or door. The heating is then turned off to conserve energy. Although the TRVs make a small humming noise while operating, I found that they were very quiet in operation. Once I was used to them, I could easily sleep while they operated.

We also found it was easy to create some basic automations in the app using the Moments feature - such as turning the radiators in the lounge on, while also dimming the map connected to the Wiser smart plug to create a cozy atmosphere of an evening. AppSpare bedroom (mostly in the off position unless we have guests), bathroom, downstairs WC, hallways and kitchen have old dumb TRV's but that works for those rooms, we have them set to some mid point on the dumb TRV's and works nicely that they heat whenever something else is also calling for heat. Ref the comments in this post about utilising existing Danfoss TRV bodies, most of my system uses old Danfoss RA's which I have converted to smart using the supplied adapters.

Banging or hammering in a system is caused by excess pressure or water turbulence in a system rapidly lifting and shutting the valve seat. If this is happening it would be advisable to get a qualified heating engineer to take a look at your system. What are smart radiator valves? Can they work with your current heating controls? How much are smart TRVs? the logic behind smart TRV's is you don't heat empty rooms this only really works if every room has a smart TRV have no minimum requirement for heating controls other than those required at the time of installation. Again you can opt for an advanced control. You may only wish to have the functionality of an internet control. Guide to selecting the right advanced controls Drayton has a range of time controls that give you different levels of flexibility. Some allow you to set a 24 hour programme that will be repeated on a daily basis, others offer a 5 day/2 day programme which enable you to set different programmes for the week and weekend, and some allow you to set a different programme for each day.Auto-balancing TRVs permanentlyand easily balancing a radiator heating system, reducing home energy bills. You can use an app on a smartphone or tablet to turn the heating on or off, and adjust the temperature without needing to be near the home – as long as you have an internet connection. For instance, if you have gone to work and left the heating on, you are able to remotely switch it off with the touch of a button, allowing for greater freedom and control over the amount of energy you are using. It’s really easy to adjust heating schedules on the go using a smart control, which means you can reduce energy consumption by tailoring heating periods to fit in with your lifestyle and routine. must have ‘time and temperature controls’ namely a programmable room thermostat or a thermostat with separate programmer. You can still opt to install an advanced control. Existing boiler installations:
