I've just moved into a fairly old and big house. The current setup is as follows:
Two Viesman ESS boilers running in tandem to heat up 22 radiators. About 70% of the radiators are double, with the rest being a mix of single or small doubles. Two thermostats control the heating. One is for upstairs and the other is downstairs. Rarely will all radiators be on at the same time (only in Winter most probably and only for a few hours). There's also an unvented water heater.
One of the boilers is totally gone. Totally corroded and I've been advised to replace both as they are fairly old. I've been informed that the piping etc is in excellent condition, so it should be a case of boiler replacement only. I've also been advised to go for a stainless steel replacement as these last longer.
I assume I only need a system boiler and not a combi.
Do I go for a single large capacity boiler or should I stick to having two boilers in tandem? Can anyone recommend what boilers to go for? I need boilers that will heat up the radiators quickly and are suitable for big rooms.
