Aug 13, 2018 · Condensing boilers cool the exhaust gas so much that they can be vented with CPVC or Polypropylene (plastic) pipe, instead of the steel venting required by conventional boilers. They produce cooler exhaust because the extra heat has been harvested and transferred to the water in your heating system.
Gas condensing boilers A gas-fired condensing boiler is one of the most economical and clean ways to heat your home, reduce your monthly heating bills and lessen environmental impact.
A. Description: Boiler shall be natural gas fired, fully condensing, fire tube design. Power burner shall have full modulation (the minimum firing rate shall not exceed 75,000 BTU/HR input. Boilers that have an input greater than 75,000 BTU/Hr at minimum fire will not be considered) and discharge into a positive pressure vent.
Efficient Warmth. Conventional heating systems waste energy through heat loss vented into the atmosphere. Rinnai Condensing Gas Boilers recover heat energy discharged into the flue and return it to the heat exchanger for maximum efficiency. One of the highest AFUEs (Annual Fuel Utilization Efficiency) in the industry.
When a Flue Gas Heat Recovery System is fitted to the boiler it becomes a condensing unit. So, a boiler that takes its water supply directly from the mains and produces heating and hot water for your home from one compact unit is a Combi boiler and with the addition of a Flue Gas Heat Recovery System it becomes a condensing unit too.

“Should overheating occur or the gas supply fail to shut off, do not turn off or disconnect the electrical supply to the circulator. Instead, shut off the gas supply at a location external to the appliance.” Slantfin recommends the installation of a carbon monoxide detector in the boiler room for all installations.

Non-condensing boilers most commonly include traditional cast iron gas and oil boilers which have anywhere from 82% to 87% AFUE. Due to restrictive cost of condensing technology (at present) and proven track record of cast iron boilers, they still remain very popular for heating projects on a budget.

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.
