Hi,
I've just had an excellent plumber/heating engineer round to have a talk about replacing my existing combi boiler.
We agreed that the best solution for my 5 bed/3 bath house would be a system boiler + unvented cylinder.
As a Worcester Bosch installer he recommended the 30cdi and either a 210 or 250 litre unvented cylinder, make to be decided, but I'll probably go for either the Vaillant uniSTOR or Santon Premier Plus (maybe the Plumb Center centrestore version). I think the Megaflow is just a little to expensive for what appears to be no benefit over the others.
One thing that confused me was that he said he would need to replace my existing programmable room thermostat (a 7 day digital Honeywell) with a non-programmable thermostat.
I did question him further about this and got the impression that the boiler/cylinder came with the required controls and so the programmable thermostat wasn't needed.
My understanding is that the boiler will have a programmable timer to control the times that the boiler heats up the water and the cylinder will have a similar timer to control it's heating.
Surely the point of a programmable thermostat is that it can regulate the temperature at different times of the day without having to turn the boiler off!
My current old Saunier Duval boiler has one of those circular analogue type switches, which is always switched to constant so the boiler is always on, and is therefore controlled by the programmable thermostat.
Am I missing something?
