Designed specifically for UK homes, the new Auto-balancing TRVs from Drayton fit onto standard pipe sizes, which means they’re easy to add to your existing system with little or no pipework changes. If you have a regular schedule, you may well benefit from being able to program a heating schedule. conventional boiler. It’s used in conjunction with a time control and whilst it cannot influence the temperature of the water entering the cylinder, once the set point for the whole cylinder is achieved it can stop the call for heat.

Yes, for a combi boiler there’s no need to control the hot water as it’s on demand so you will typically use a single channel controller. A conventional boiler stores hot water in a cylinder, so this also needs to be controlled for time and temperature, typically using a two channel controller. First, remove the valve head, then, use the presetting tool to unscrew the gland seal. Finally, screw in the new gland seal remembering not to over tighten. Now you’re done you can re-attach the valve head. If you find yourself working on a heating system that is exposed to the elements and is therefore likely to feel the full force of any cold weather, protecting the pipes against freezing can stop a system breakdown.

When taking a digital thermostat from a cold van and installing it in a warm home, you should be aware that it won’t respond instantaneously. The miGenie thermostat and miGenie gateway are pre-bound to the miGenie controller so they just need to be positioned in the best place for wireless communication. To help with this, there is a built-in signal strength indicator. The target drop in temperature from the flow to the return pipe is 11˚C. If the temperature is different you need to adjust the flow rate, dropping it to increase the temperature drop and vice versa. Wi-fi radiator valves cannot communicate with a smart thermostat (so they cannot turn your boiler on and off).

It can sometimes be necessary to replace the TRV head to provide improved control or to simply enhance the radiator appearance and this can be done without changing the entire valve body. Although you can use a smart thermostat to control your home’s heating, a smart radiator valve allows you to operate the radiators separately. They are a great addition to any central heating system because they allow you to have complete control of any radiator via a smartphone application or even through voice commands and other smart devices.

This means you can remotely set the thermostat and smart radiator valves temperatures. You can even set the exact temperature with smart radiator valves, instead of the 'rough' temperature as you do with thermostatic radiator valves. Limited functionality without a smart thermostat You need a compatible smart thermostat if you want to get everything that a smart radiator valve has to offer, as this will allow your valves to communicate with the boiler to turn it on and off. We reached out to the biggest brands to find out more about support policies, and some are far better than others. Neither of the boiler manufacturer's smart TRVs are compatible with home automation devices such as Alexa, IFTTT and Google Home. For heating, both relays can act as simple on/off switches, but they also support OpenTherm for compatible boilers. Where possible, you should use OpenTherm, as this technology can adjust the boiler’s output automatically based on demand, using the minimum amount of gas required to get your home up to temperature.

A cylinder thermostat is used to measure the temperature of the hot water stored in a cylinder when using a When batteries are running low, a low battery icon will flash in the display. During this time, miGenie will function normally.

Thermostatic radiator valves (TRVs) are an important part of the central heating system, as they allow householders to control the temperature of each individual room through the radiator.The boiler branded heating controls are quite expensive, although the Worcester Easy comes with upto 10 years of manufacturer’s guarantee when fitted with a compatible Worcester boiler You set the temperature in degrees celsius This is easier to use and more intuitive than the 0-5 scale on TRVs. Alexa and Google Home support means that you can control your heating using your voice. Alexa recognises individual rooms so that you can adjust the heat automatically, and you can also find out what the temperature is in each room. Heat Pumps are also supported and selectable in the app as the available heat source. Underfloor heating is also supported: wet systems need the Underfloor Heating Controller; electric systems can use the Drayton Wiser Eletrical Heat Switch. The Drayton product range offers a solution to meet all of these except flue gas heat recovery as this is provided by the boiler manufactures.
