I have a question for the learned folks on this board. I'm thinking about buying an insulation jacket for my hot waterboiler with a DHW coil. It's made from a highly heat resistant material with an R value of 5.8 and it's custom made for certain boilers. At $ 350.- the cost is quite substantial and I'm wondering if it's worth it. I'm sure there will be some savings in terms of energy consumption and run time, especially in the summer time, since I have to keep my boiler on all summer for DHW. They claim an average saving of up to 700 liters of oil per year which may or may not fall in the same category as the car manufacturer's mileage claims:rolleyes: I also installed a Beckett Heat manager last winter and in conjunction with a boiler jacket the results may not be too shabby. I'm very pleased with the heat manager, it has reduced my cycling very substantially and it has also reduced my oil usage. Any comments are much appreciated.:) Here's the product I'm thinking about buying [url=http://ecohomesolutions.ca/]Eco Home Solutions - The Boiler Jacket Insulation Kit[/url]

I have an older HydroTherm HW boiler feeding 6 condos that was never equipped with a LWCS. Now my insurance company is requiring one and I can't find one that works on a millivolt system. The system has 6 circulators and relays wired to seporate panels/meters that are controled by 6 t-stats using millivolts. How can I get a 24v LWCS to work on my millivolt system?
