Buying A Used Gas Boiler Can Save You Money
Anyone who has ever tried to replace the heating system in the house will know how expensive it can be, with many new residential gas boilers costing at least $3000, with the best modern gas boilers, especially the modular combination type boiler costing up to $5000 or even more. Because of this high cost and expense many people take a look at buying one of the many different kinds of used gas boilers now available on the market. This can be a great way to get the cheap gas boiler, or one at a discount, and as long as you go about it the right way you should have no problems. This article will take a look at a few things to consider when buying a used gas boiler and how to avoid some of the pitfalls when buying a secondhand residential boiler for your home.
The first thing to realize is that it may be very difficult to buy a used condensing boiler, since these are a fairly modern invention and many people who installed a gas condensing boiler are still using the same model and have not yet recycled it for sale in the used gas boiler market. The good thing about a residential gas condensing boiler is that it is very energy efficient, which means it can save on fuel bills over the long term. By buying a used boiler you may not be able to take advantage of this fact, which is something to bear in mind.
It is also a fact that many used gas boilers are not combination boilers, with a secondhand combination boiler often being hard to get hold of. However, these are not as rare as used condensing boilers, and by doing some research and taking some time it may be possible to find a good quality used gas condensing boiler at a decent price. You will need to remember that a combination boiler is a much more intricate mechanism in a straightforward gas boiler which uses a hot water storage tank, and therefore may need to be reconditioned and service to a great degree before it becomes suitable for use in a residential environment.

Another major consideration to bear in mind is that a secondhand residential gas boiler will probably need to have parts replaced on a fairly regular basis, that this will very much depend on how well reconditioned unit is. Some of the things that you may need to look at include gas boiler filters, and replacing the boiler heat exchanger. The best types to get is either a modern aluminium heat exchanger, or a steel heat exchanger, both of which can give very long-life and help to improve the efficiency of the boiler overall. In terms of overall efficiency, most used residential boilers will have an efficiency rate of around 80% to 85%, which is much lower than the usual 95% efficiency which comes from a new high-efficiency condensing boiler. Another spare part that you may need to look at buying is the gas boiler thermostat, with a replacement boiler thermostat often being a fairly expensive part to buy. You may also want to replace the boiler control panel in order to make sure that all the boiler functions are working correctly, including automatic fire up, and that the pilot light and electronic ignition are also functioning properly. For high quality, take a look at the Noritz tankless hydronic boiler, a natural gas unit with 150,000 BTU output and dual flame burner. It has dual temperature controls for domestic water heating and central heating, running at an 83% efficiency. Also consider the Peerless high efficiency combination boiler [combi boiler]. With a 160,000 BTU output and running at 93% efficiency. It is a gas condensing boiler that provides hydronic heat and domestic hot water. The heat exchanger is ASME rated, while the boiler has panel controls and expansion tank, the unit being suitable as a wall mounted boiler running on both natural or propane gas. and giving LoNOx output. As with buying any kind of gas boiler, it always pays to buy boiler from a reputable company, both in terms of the boiler supplier and the actual boiler manufacturer. Make sure that you get a warranty or guarantee with your used boiler purchase in order that any problems after installation will be dealt with fairly quickly. When buying a used boiler take a look at what is included in the deal, especially to see whether important parts such as the heat exchanger and automatic thermostat have been replaced prior to installation. |
