Hello Everybody I'm new
I started a couple of years ago with 30 58mm tubes into two tanks
plus a pumped bypass into a double rad inside our cold Cornish cottage (heat dump). This worked fine with bypasses from march as early as 1o'clock on sunny days. But soon as the sun started to drop
my system struggled to heat even one hot cylinder, to many trees (oaks) on my southern boundary. they stayed in leaf that year till November. Now I know I'm mad cause in January this year I took delivery of a further 60 58mm tubes and almost straight away I melted through a pipe I had used hep20 from a divert er valve to the first cylinder coil, it's funny now I was on the roof at the time slating in our new extension when BANG! burst melted pipe it was running at 90c earlier. So I quickly covered up my 3 panels with dust sheets and ordered some flexible copper pipe screwfix next day I had it running by midday, and the two tanks topped out at 53c bypass running into my rad everything fine until next day. My bypass rad was running at 60c and climbing this was in march, I needed a larger heat dump. I happened to have a heat xchanger from a old dead oil com bi boiler, and it was on my mind could I connect it into my central heating return and would it work! work! did it work it was fantastic,I had connected it across the flow and return to my bypass heat dump and used a pipe stat to turn on a relay which turned on the boiler pump only and also turned on my underfloor zone in my cold cottage Wow instant heat into my boiler/ rads and floor zone cannot stress how well the heatxchanger works. By the end of the summer I had 6days when it was to hot for my heat dump and I had to turn on my other two floor zone's can't go thought that again. But I have a plan which involves moving my rad outside and a summer? switch a pipe stat and valve.And for the near future some sort of power failure back up on a shoe string please any Ideas.
