Good one.... :lol: :lol: :lol: ...and he will be using a stirrup pump to circulate too no doubt... !! ROTFLMAO . .

. . Damn it, I covered everything but!!!! :? . .

. . Correct, correct, correct... I go along with what you are saying but how do I get out of it now? I "contracted" with him to supply a system that works, and he is still trying all sorts to get it to work. Yes, I would have preferred to have someone who knows what they are doing to...

. . Well have been on phone to plumber again tonight and he tentatively admits the system is wrong and is suggesting taking the ACV tank out. I think it is as a result of me emailing back to his office and letting the office know what is going on every time he visits. Now talking about...

If the tank was up to temp, without an injector tee the cold water in the return from the rads would (actually is!) "reverse flowing" through the coil when the pump kicks in and draws heat AWAY from the tank and round the rads. If you trhink about it like an electric circuit the tank and the...

. . Yes, the ACV guys told me the coil is 10x the resistance of the correct tappings. Told the plumber and he said "what do you mean?"!! Yes again, when the stove is out the heat leak rads actually draw heat OUT of the tank via thermosyphoning cos the rad is higher than the tank...

. . Stove has been going for 2 1/2 hours, the tank is warm, not hot. It will be a lottery who gets the ONE luke warm bath tonight!! The heat leak rad return pipe is too hot to touch and I have used 3 buckets of coal!! The room rads haven't been on either. Just been in the loft, the heat...

. . Ok, piccy of rads pump for woodstove looking down onto floor. (should have rotated piccy really.) Pipe in order left to right:- 1 - Oil return flowing up piccy 2 - Stove return with pump (hidden by floorjoist) flow up piccy 3 - Stove flow from stove after tee'ing off from...

Sorry, I was refering to the pipe stats when I said near the tank. The rads pump for the stove is just under the floorboards on the return to the stove, about 6 feet before the so called "injector tee" in the piccy. (will post a piccy of the pump in a mo.) Yes, the pump in the piccy is the...

The stove is a Woodwarm Fireview 20kw fully boilered with split saddle and roof boilers. Yes, it has it's own circulation pump for the rads that kicks in with the pipe stats. located near the DHW tank http://www.metaldevelopments.co.uk/woodwarm/

. . Ok, HETAS registered guys, a question.....(or anybody with more knowledge than me!!) the heat leak rad "upstairs" piped up to a wood burning stove. Feed pipe up to rad branches off to the vent and the return back "downstairs". This is to cater for a power outage in case the CH pump cannot...

. . Just to keep you posted on what happened after the plumbers visit yesterday He came and re-opened the heat leak rads valves and repositioned the high and low pipe thermostats. I have left them as they were for now. When I got home the hot water tank was at about 65 degrees and the...

There are plenty of "not so pretty sights" with this installation I'm afraid... and for a job thats costing me £13k plus I would have expected a decent job..... :( Thankfully it's a "balance on completion", which at the moment, 6 months down the line, it isn't! . .

The woodstove is just through the hole in the wall. See how many 90 degree bends you can count that the flow from the stove has to negotiate before it gets to the tank!! Also note the 50mm rise from stove to tank!!

Ok Norcon, points noted on the connections. I think the guys at ACV (Stuart) was trying to avoid too much re-piping. They also suggested the 600 model.. :( You say "giving hot water priority", sorry non comprende on that one... the oil boiler side is fully pumped and it tees off, one to the...

The diagram in the instructions have a couple 2's and a 5 on each side. Is it purely the "upper" connections are flow and the lower ones return? On a radiator the ideal connections are top to bottom, end to end I believe, in this case would it be better to go in on one side of the tank high up...

. . He's been! he's been!! Haven't seen what he's done but has at long last spoken to the stove manufacturers about the issue of lack of gravity circulation.... he's waiting for them to come back to him. Has moved the hi and low pipe stats, not quite sure why but we will see. Was on the...
