5 Common Myths About Saving Energy and Money - This Old House

In that case, it could take 12 to 15 years to recoup the $2,800 cost of installing a gas-fired tankless water heater. (Fortunately, these heaters last 20 years or more.) For about the same price, you can buy an Energy Star tank-type water heater with a condensing gas burner or a hybrid electric heat pump.

Condensing boiler - Wikipedia

Condensing boilers are water heaters fueled by gas or oil. They achieve high efficiency (typically greater than 90% on the higher heating value) by condensing water vapour in the exhaust gases and so recovering its latent heat of vaporisation, which would otherwise have been wasted.This condensed vapour leaves the system in liquid form, via a drain.

Exhaust Gas Emission Improvements of Water/Bunker C Oil

In this study, emulsified fuels were prepared and produced by blending 0%, 5%, 15%, and 25% water with Bunker C oil to reduce the amount of air pollution emitted by ships and replace oil resources, and they were applied to an actual marine boiler to analyze the exhaust gas. The fuel effects on the improvement in exhaust gas emissions were as follows: The oxygen (O2) concentration increased by

What are the different types of gas boilers?

CONDENSING BOILERS Every gas and oil boiler installed in Ireland's must be a condensing boiler by law regardless of whether it is a combi, regular or system boiler. Condensing boiler work by condensing water vapour in exhaust gases which recover latent heat that would otherwise have been wasted or vaporised through the flue.

Are Tankless Water Heaters a Waste of Money

Apr 06, 2012 · The researchers in the Minnesota looked at natural-gas heaters; that certainly makes sense, since natural gas is one of the two most common fuels used for heating domestic hot water in the U.S. (The other is electricity.) Electric-resistance tankless water heaters are much less common than natural-gas tankless water heaters.
