Hello All,
My Worcester Bosch 240 boiler is currently hanging off the wall and after many years of reliable service is going to the boiler graveyard. My plumber has recommended that I go for a Glow-Worm 38 CXi on the basis that we have a 5 bed/2 shower house. The only problem is that we never use both showers because if one (on the 2nd level) is running you simply don't get the water pressure in the other (on the 3rd level) - in fact you don't get any water from it all.
I have checked the water flow in the rooms and the following is the amount of water in 20 seconds:
Downstairs sink: Cold 3.3L; Hot 2.5L
2nd level bathroom sink: Cold 4L; Hot 2.7L
2nd level bathroom bath: Cold 4.75L; Hot 2.8L
2nd level bathroom shower: Cold 3.5L; Hot 2.3L
3rd level sink: Cold 3.3L; Hot 2.3L
3rd level shower: 3.5L; Hot 2.3L
So, I am wondering whether or not it is worth getting the 38CXi boiler given that we don't use both showers simultaneously. Clearly it would be preferable to use both showers but given that we don't should I just go for the 30CXi?
One thing I'm not clear on is whether a boiler can close the gap between the cold flow rate and hot. I know a boiler won't pump water but does it regulate the amount coming out to ensure it's sufficiently heated so if I go for the 38CXi will I get more hot water in the 3rd floor?
Finally I've been quoted £1400 for the 30CXi and £1700 for the 38CXi supplied and fitted? Reasonable?
Sorry, one final point, we do have a lead pipe coming in to the house with an old tap on it. I know this won't be helping but is there anything I could consider that would increase the water pressure without costing too much?
Thanks
Ian
