Hi, I'm thinking of having the CH boiler changed. I've added all the radiator kW and allowed 2000W for water and this comes to 25kW. We use lots of hot water so maybe 2000W is too low - but we do not like hot bedrooms and tend to live in the kitchen diner area rather than the living room. The house is quite big and 20 years old. No cavity wall insulation but fairly well insulated loft and boarded out too for storage. Hot water is pressurised storage tank 170 lites.
I was thinking of a Baxi Megaflow but heard bad reports about circuit board failures. Now thinking of Viessmann 100 but read of 200W with weather control rather than room stat. All radiators have TRV's except kitchen diner where room stat is which is digital type.
Baxi - parts are lower cost and easy to come by if required. Viessmann I've no idea - but I guess parts will be more expensive though readily available but I hear mostly Viessmann is a good reliable boiler and of course 200W offers weather control.
Existing boiler is 20 years old and I'm thinking of trying to save heating costs.
Another boiler is the Alpha and I read the lower cost Biasi is also reliable.
So do I go for the lower cost option and be prepared to bin it if it proves unreliable or the higher end with Weather control?
My current boiler has proved reliable for 20 years - the odd thermocouple failure - its a Myson.
What do you suggest?
Thanks for any reply.
