"They can't. It is up to us to educate the consumer and downplay warranties while putting the emphasis on good installation and regular maintenance.
Most major failures are result of pour application, installation and total lack of…"
"More still. It is marketing overruling common sense and contractors going along for the ride.
The best consumer protection is an educated consumer. I stopped selling "warranty" a couple of decades ago.
Regardless of what it…"
"Dale and I are referring to high efficiency condensing boilers designed to recover the latent heat of vaporization in a secondary heat exchanger designed for acidic condensate and capable of the highest combustion efficiency available in a gas-fired…"
"Though Viessmann is relatively unique in the application of Lambda technology to condensing boilers, most condensing boilers (I have installed 12 manufacturers) burning natural gas will not have to adjusted for altitude up to 6,000 feet or so.…"

What will the combination tankless and ThermoDrain cost installed?
Payback and ROI for a retired couple in…"
"Like all tankless water heaters, but as the OP states the ground water is cold so in cold climates extra care must be taken to assure the volume of hot water, which will diminish as ground water temperature drops, is adequate for the…"
"We specialize in condensing appliances but few residential applications warrant a tankless water heater. I would install a 50 gallon tank type heater for a natural gas application such as yours. You can likely afford the $35/month cost of operation…"
