We also assume the use of gas as this is the most widely used fuel, and can obtain the most efficiency gains from modulatingĬontrols. The open therm protocol, but will use a similar ‘bus’ type communication. When referring to room compensation I’m referring to any internally located controller that modulates the boiler flow temperature to achieve the required indoor temperature, this may or may not use This can give an accurate indoor temperature without using an indoor sensor, however indoor sensing and influence is available. On the Vaillant range, the CDI Worcester and the Viessmann 200 boiler. There are small variations in comfort and efficiencyīut why not aim to maximise both! So what method is best for your heating? Room compensation, weather compensation, or to what level of both?įirst let me explain that when I refer to weather compensation otherwise known as 'weather comp' I’m referring to ‘intelligent weather compensation’ like that found
This is a strategy to help people come to a more solid conclusion and highlighting the benefits and pitfalls of each method.
The main advantage of these controls is lower boiler temperatures which gives more condensing efficiency, and much less boiler cycling which extends boiler life and again further One that has no real right or wrong answer, and they most certainly overlap, but there are some situations where one will outperform the other, It’s all about a balance between comfort andĮfficiency. I ts becoming an ever more increasingly popular question within our industry (well amongst ecotechnicians anyway), and
