Is the boiler time controllable and programmable, if so, how many times per day can it be set to come on etc?
Yes, our condensing boiler can be connected to any clock available on the market. I have deliberately not put the clock inside the cooker, you can fit one where you want, usually in the airing cupboard. This is a deliberate policy. Clocks inside ovens tend to overheat and fail. In 10 years’ time, the clock a manufacturer bought might not be made any more and it would be difficult to alter the iron fittings. By using a standard clock, you can replace it easily if, or when, it breaks down.
