Heating etc costs
Mac: Apologies for not replying earlier, but I was waiting for about a month to see how the system was faring and how much ESB in particular I was using. The system works on a pressurised system with an expansion tank in the boiler house, whose purpose is to absorb any water expansion volume ie overflow. There is a bladder inside this tank, and it this tank which is pressurised. There is also a pressure gauge in the hotpress on the pipe carrying the water from the mains pipe. I previously had a lot of problems with my system, I had an underfloor leak, which was losing approx 30 gallons a day which did not show up until the urban coucil cut the water off during the nights in 1990/1991 or thereabouts. it was only then when we heard the radiators filling up each morning that the penny dropped. Had to get in the insurance and the cause was a kinked pipe which was left by the plumber who worked on the house entension. Sod. Anyway I asked my plumber how would I know if I had a leak with the new system as the system is mains fed and pressurised and might put pressure on a leaky seal or joint etc and having no header tank to check out etc and he informed me that if I turned off the stop valve on the feed from the mains and I had a leak the pressure would drop to zero. Thats the only way to find out if a leak has occurred ,whereas with a header tank you can just tie up the ballcock and check the water level. There is also a air outlet valve in the hotpress and also in the boiler houe on new pipes he installed.The system is working fine but another consideration is that I dont have a dual system anymore. He cut the back boiler off completely and just emptied it. Said a pressured system can't have a back boiler. I will probably change this to a gas fire in the near future as we only light it for two weeks and Christmas and a few weekends in Jan/Feb before getting fed up carrying in coal etc. I can still light a fire but I will be heating only empty steel so effectively its only something to look at. My esb reading is just over 600 units for one complete month which is magic for me and I suspect I will benefit even more during the winter when the heating is on more during the day. The radiators are unbelievably hot and the valves on them have only to be turned on about 3/4 to 1 1/2 turns to get full heat, literally in minutes. And I have a full hot water tank from about 1/2 hour after the heating come on. I had to get a new copper cylinder as the coil in the previous one was completely gunged up . Cleaning out the radiators, new cylinder, installing new system and fitting new valves to 14 radiators cost €1100 which was more than I bargained for but if it saves me even €50 per two monthly esb I will recoup it in 3/4 years and this is the kind of saving I estimate I will be making. I will wait now until the Jan/Dec billing period to see if I am on course. My bill for this period last year as €240 and it was underestimated by 300 units.
