my boiler is losing heat - it has been serviced evey 2 months - there was no soot the engineer spent alot of time servicing it - I watched him - but even he does not know why it wont heat up - it is only luke warm - and yes plenty oil in
the tank. The oil tank is a bit away from the house will this make a difference. It is an old boiler serviced every 2 months
Every two months? an Aga should be serviced every six months, firstly has the engineer checked your filters and flow to the aga? has he properly de coke the burner and bundi and changed the wicks? has he checked the pin in the float control aswell as checked the oil flow rates from the control box? all these need checking so your aga runs smoothly for the six months between services
