Hi Everyone,
This is my first post and would be grateful for any advice. I live in a very old but cold house. Have been living in the house for 17 years and heating has always been an issue. I must have spend in the region of 10K over the past 17 years and still have problem with heating and hot water. I have forgotten how many time the radiators have been balance. I have had the boiler changed twice. Every plumber has blamed the other problem! The problem is that some radiators are hot but others are stone cold and no matter how much "balancing" is done it makes little difference. The cold radiators gradually become warm or even hot after the boiler has been on for a few hours!
I have finally found a problem who appears to be trustworthy. He thinks the problem is that the boiler is too far from the radiators and that's why some of radiators are stone cold and others are piping hot. He also says due to the way the plumbing is the balancing is very difficult. All the pipe work are underneath a very old floor board with difficult access.
He has suggested that I replace the system with 2 Baxi 618 system boilers and also add a Grunfos UPS2 25/80 pump and a 40KW low loss header. He obviously need to install 2 vertical flues. All at a cost of £4200.00
Considering my previous experience, I am naturally suspicious although he seems a nice guys and has done other works for me and quality has been very good.
What do you folks think and specifically what is the advantage of having 2 boilers? He says one would be for heating and the other for hot water but they can also act as a back up if one fails.
I have had a look at the Screwfix and they sell the boilers for 690 each and the pump is about 250. If that is the case is 4200 too steep or it this the going rate for installation and other consumables?
Thank you so much
Sean
