evohome means you’re always in charge of your home heating & stored hot water – wherever you are.

At its heart is the evohome controller, your simple to use control panel that lets you set the temperature in every room in your home – from anywhere in your home.

With ever increasing fuel bills and the need to be as eco-friendly as possible, it’s important that we all look for ways to save fuel and carbon emissions – and money!
All boilers now have to be condensing boilers and this represents a huge step forward in environmentally friendly heating, with fuel savings of up to 35% compared to conventional boilers.

But there is a way to save even more – up to 15% in fact, with just a simple outdoor sensor and some very clever Weather Compensation controls, available with the Vitodens range of condensing boilers.
For a relatively small investment you’ll not only save up to 15% more fuel each year but you’ll also enjoy an incredibly comfortable home – with a pleasant indoor temperature – whatever the weather.

Heating – the basics
Our homes need heating, to replace heat lost through the walls etc. The colder it is outside, the more heat is lost and the more we have to heat the building, to replace that heat, especially in the winter when the heat loss is at its highest level.
This basic explanation is fundamental to understanding how an outdoor weather sensor can help to heat your home in a more efficient and cost-effective way.

Weather compensation controls work by ensuring that the boiler burns the exact amount of fuel required to match the heat lost from the building. The house will always be warm (at the desired temperature) and will never be too hot or too cold. Weather compensation significantly improves
efficiency under partial load conditions and is especially relevant for the UK climate, as for two thirds of the year the boiler will provide only a fraction of its maximum heat load, which means the boiler temperature is reduced for the majority of the year, while still maintaining a constant room temperature of 20ºC. Only around 15% of the homes total heat energy usage is consumed during winter temperatures between -3 to -10ºC.
