The simple answer is YES. Your boiler not only gives you heating and hot water but it has the capability of killing you and your family, so PLEASE get it serviced.
We can service your boiler when it suits you so your dont have to take time off.
This may sound silly but make sure that it is being told to work. Is the timer on ? is the thermostat up? If this doesn't work just give us a call and we may be able to help over the phone.
Is the water hot or cold? is it soapy or smelly?
If its cold then turn off your stop cock (usually found under the kitchen sink)
If its hot and you have a hot water cylinder then look for the pipe going to the bottom of the cylinder and turn the valve off. After that call us and we will take care of the rest.
