I agree an accumulator and combi sound like a good idea. However, we find that it is difficult to fit a suitably sized accumulator and combi in a vertical plane - the combi takes up too much room with the min clearances etc to get a decent sized accumulator underneath.
The accumulator is no bigger than the cylinder he was looking at. He has no option, unless he pays around £1K for new water main, to go accumulator/combi. Fate accompli !!! It is also the cheaper option too.
The application of a potable accumulator to augment the flow of water in a hot water system is covered by a patent.
Try and get this patent to stick!!!!! Did they patent the wheel as well? DPS are selling accumulators as well. I'm sure they are paying no royalty to anyone. I'm sure Reliance is paying nothing to anyone when it sells an accumulator.
Potable accumulators are made by Flamco and a number of other manufacturers but they have all so far restricted their sale for this purpose because of the patent. Doctor D is right in saying they are available; however if you fit them for this purpose you may find yourself being the test case in the UK.
Garbage!! People have fitted them way before a patent came along. Restricted sale? In what way?
I wouldn't take that risk if I was fitting 100 a week or 1 a week. I will let Doctor Drivel do it and see what happens.
We obtain all of ours through GAH. Their unit has a diffraction diffuser to help ensure that the water is rotated in the vessel, and we get good support from them. They are WRAS approved. Ordered 12 this week!
