Condensing boiler<\/h5>

Although the installation of condensing boilers has been mandatory since 2005 most boilers do not operate in condensing mode without specific conditions being met. If you can drop the boiler supply temperature to 55 deg C (You might need to measure it) and still provide adequate hot water performance you will likely have your boiler condensing more frequently saving money. If you find that hot water is not adequate or house heating is not adequate adjust temperature up 5 degrees at a time to achieve the lowest supply temperature that will promote boiler condensing.<\/p><\/div><\/div>\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t

Modulating boiler<\/h5>

Although modulating boilers have been available for many years they are not always installed by default, but having a modulating boiler allows the opportunity for weather compensation to be enabled saving energy and increasing overall system efficiency.<\/p><\/div><\/div>\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t

Legionella cycle<\/h5>

Legionella disease is a lung infection that you can get from inhailing droplets of water containing the bacteria. The bacteria can survive and multiply in water between 20 and 45 degrees. The bacteria does not survive in temperatures above 60 deg C. A regular Legionella cycle which takes the water temperature in a hot water cylinder above 60 degrees will prevent the risk of Legionella.<\/p><\/div><\/div>\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t

Room temperature controller<\/h5>

A room temperature controller in its simplest form can just switch on and off the heat source. More complex controllers can provide different temperature setpoints at different times but for optimal control the room temperature controller should provide a modulating signal to the heat source.<\/p><\/div><\/div>\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t

Weather compensation<\/h5>

There are a few different variants of weather compensation and in its simplest form the flow temperature of the heat source will adjust dependant on what the outside air temperature is. The reason for this is that as the difference between the inside temperature and the outside temperature increase more energy is required to be injected into the house to make up for that greater loss. Subsequently it makes no sense for the heat source to run at a constant temperature and this is the principal of weather compensation. Basic weather compensation will provide one curve others will provide many curves that can be selected to match the building fabric losses. Some manufacturers also provide load compensation where it can take into consideration the required room setpoint and adjust the curve to compensate and deliver the correct amount of energy. fine tuning of weather compensation can take some time to get the system optimized. Weather compensation is only available on a heat source that can modulate its output.<\/p><\/div><\/div>\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t\t<\/div>\n\t\t<\/div>\n\t\t\t\t\t<\/div>\n\t\t<\/section>\n\t\t\t\t\t<\/div>\n\t\t<\/div>\n\t\t\t\t\t<\/div>\n\t\t<\/section>\n\t\t\t\t<\/div>\n\t\t","protected":false},"excerpt":{"rendered":"
