Aug 19, 2019 · The boiling point of water at atmospheric pressure is 100°C or 212°F. The design is fairly similar to a fire-tube boiler, but instead of the furnace heating fire tubes to heat water in a tank, the furnace heats water tubes inside the furnace. In the same way, a fuel source is burned in the furnace, causing the water tubes inside to heat Get Price
When you replace an older furnace or boiler with a new 90+ AFUE appliance or a heat pump. In this case, the heating appliance will no longer vent into the old chimney, and if the combustion water heater is present it will now vent through an oversized chimney. This oversized chimney can lead to condensation and inadequate draft.Get Price
These systems can be purchased in an integrated form, incorporating the boiler and water heater with controls, or as separate components. Gas-, oil-, and propane-fired systems are available.
