Posted at 29/7/2002 00:18 by equaliser PaulismynameA few questions on your old Potterton system, as 5 years is not a long time and from my experiance Potterton are reliable I still run a 18 year old system on a wall mounted Poterton 50k BTU. Your statement that the pipe work is too small and the Boiler overheated ? 1 Boilers have internal thermostats to regulate heat exchanger thmperature, so even considering less than ideal water flows the boiler should not self destruct. The only outcome would be poor heat flow into water and a bit of wasted gas heat input ( wasting a bit of money) 1a Have you had the pump cheched ? 2. Was this boiler a cast iron heat exchanger type. 3. was the system fully pumped or pumped heating & gravity Hot water a new instalation 5 years ago would be fully pumped if it is 15 years + then graverty. In short it does not sound that you need a complete new system but a new cast iron boiler simple and robust cost for 60,000 BTU should do a large house less than 500 pounds from Wickes Halstead boilers make them for wickes so check their web site for larger units if needed. cost more direct though. I agree with the others that you are in for a rip off if not carefull you should be able to sort this for 800 to a grand without tearing up the house. Yes it would be nice to fit a new system in which case condesing combi boilers could be considered but new radiators and thermo valves will be needed as well. Something else you will hear is a recent change in building regulations that now insist that, if a heating system is replaced then it must conform to a energy eficiency standard. This has a lot of issues on boiler control ( this hits gravity systems but not fully pumped. and you need thermo rad valves. you may need an instaler who is willing to ignore this or DIY My view, to control expenditure and get value for money a cast iron boiler fully pumped and a few rad valves should do it. but if your system is gravity then some changes to pipes might be needed. Good luck. |
Posted at 28/7/2002 15:40 by dss One of the most regular faults on a system which our guys go out to, apart from the thermocouple ,is the failure of a valve,either 3 position diverter on such as a y plan system or more likely on a big house system a port valve for the upstairs and down stairs.Do you have more than one thermostat? can you time heat upstairs and down seperatly? The port valves will be probably near to the boiler at a point where upstairs diverts away from downstairs.It will be controlled by either time,a stat or both. It will have a short shiny flex leading away from it and probably a makers plate of Honeywell or Danfoss.It is a silver box 3"*2.5"*2" and appears to be attached to the pipe almost like a Limpit (or is it a Limpet!) If it is faulty it will be hot at one side and cold at the other as the pipes lead into it.The result of this having failed is that you boiler is basically trying to push hot water into a "brick wall" since the valve is a very efficient stoptap when closed. |
Posted at 26/7/2002 23:25 by i know nothing Paul,Just fitted a 80,000 BTU Combination boiler for £800 including labour. Changed one radiator (cost about £25 only a small one) and five TRV's (Thermodtatic Radiator valves, decent quality) which were approx £15 each from B&Q, this I did myself as the plumber had drained the system down. It took me no more than 1 hour to complete this task. He spent the morning changing the boiler and the afternoon charging (and flushing and adding new chemical) the system. The combination boiler is 20,000 BTU more than what is recommended, why? because a 60,000 BTU boiler would not heat enough water for the shower quick enough. For an extra £150 I wanted the bigger boiler. System works a treat and I'm very happy with it, would have no problems recommending such a system. Boiler is made by Bosch (doesn't show Bosch on it, different name, but part of Bosch Group). I did have to add a thermostatic valve (preferable over a pressure reducing valve) to the shower, cost about £175, again beware, some people will try and sell these for £350, find out what you need and go to a Builders Merchants for one. So all in all, I would say that £3500 is a con. I would take issue with one point you raised concerning the pressure of hot water from a combination boiler, they restrict flow, so pressure may remain constant but you get less of it, watch out for that one, that is the sole reason why I opted for a 80,000BTU boiler, to get the increased flow rate.
