I've recently had a new condensing boiler fitted, a Valiant 828 as mentioned and like everyone am extremely pleased with its operation. However when the timer switches the boiler on there is a large noise like a foghorn when it starts up !!! I've listended to it outside and trust me, it is loud. Anyone got any clues why this may be ? :?:
Using Natural Gas or Propane with a high efficiency boiler is the way to heat your home A hydronic heating system that uses radiant technology is the best heating system that you can have. With proper installation technologies you can be heating your home or business with water that rarely needs to be more than warm in temperature. Because of this a condensing boiler is the heat plant that will produce the warm water you need to heat with at ultra high efficiencies. I have personally installed many of these boilers and have had then running in the very high 90% efficiency range. This will get you the most BTU's possible out of your natural gas or propane.
