Hi there,
I moved into my end of terrace three bed room house about a year ago and I installed Grant 15/21 oil conventional boiler to run my eleven radiators (all with thermostats but all at maximum). Oil usage has been around 1700 litres with about 200 still in the tank from that. I am working on what I still need to insulate as the house is often far from warm.
In terms of the usage I have left the Grant at the output the plumber suggested, with the dial set to about a third of maximum power output. The thermostat for the house is in the hall but I had to move it closer to the transmitter (its wireless) as the signal kept dropping. Its currently set at 20.5 C although the house never really reaches that temp even if the heating is left on all day. We close the door next to the thermostat as the back of the house (two story extension) is quite cold and with the door closed the rest of the house is warmer.
So, my question, should I up the output of the boiler with the thinking being the house might reach the temperature quicker and it will then keep it there occasionally adding hot water to the system. Or should I leave it as it is although the boiler maybe on more trying to reach the unattainable temperature?
Obviously I am concerned with oil usage so I don't want to burn loads more. Whats the best approach?
Any help is greatly appreciated.
