What Should You Replace Your Old Gas Boiler With?

By Edited Sep 4, 2015 0 0

Gas Boilers are an effective tool to heat the water you use to bathe and clean up, and provide the necessary higher temperatures needed in your house on cold winter days.

They have been in use for a long time in domestic situations and deliver the necessary results with satisfactory efficiency.

However, with gas prices steeply rising, most families suddenly find they aren’t able to afford to run these boilers and have begun looking for replacements.

Though it isn’t easy to switch over to another boiler type and get used to its performance instantly, there are many variations you could try. Important factors to consider before you look for a new replacement for your traditional gas boilers are;  cost effectiveness, size constraints in your bathroom or area where your old boiler sits, the efficiency you are looking for, and what temperature you are looking to achieve with your boiler. There are many choices that could match your criteria.

A More Efficient Gas Boiler

Modern condensing gas boilers are much more efficient so you burn less gas for the same amount of heat. Alternatively consider a combi-boiler which is a special kind of gas condenser boiler that generates your hot water on demand rather than sending it to be stored in a hot water tank.

An Oil Fired Boiler.

What is the point of going for an oil heated boiler when I already have a gas boiler, which is very similar? – You might want to ask. However, there are many varieties of oil fired boilers that combine biodiesel with standard heating oil in various ratios and provide you a lot of carbon-efficient heat. With these oil fired boilers, you can save on your fuel costs and produce fewer carbon emissions if you can find a suitable bio-oil boiler and supplier.

Biomass Boilers

Biomass boilers run on fuel that is supplied when you heat logs, barks, agricultural waste, and pellets made of sawdust. Though there are carbon emissions with biomass boilers but the carbon dioxide would be going back into the atmosphere anyway when the dead tree cells decompose naturally.

These systems have a 90% efficiency rating and make sure you can not only boil water for bathing but also heat your home suitably with the boiler. A note of caution: make sure you use only dried plant material rather than green wood. The water content of non-dried material is too high for efficient combustion.

Wood-Burning Stoves

These are a variation on biomass boilers, but are designed to burn wood, coal or any other fuel you can find. You can even make paper logs and burn those in one. They burn at much higher temperatures than an open fire would and some have a built in heat exchanger that allows you to run your heating off them. If you have a source of cheap firewood or straw then a wood burning stove might make sense for you.

Electric Heaters

Electric heaters are cheap, are excellently designed, and provide with efficiencies up to 99% depending on the design you choose. Most electric boilers are well insulated and operate on a separate electrical circuit. They have no emissions, miniscule hazards, and are generally compact and can be used in very small apartments. However if you are concerned about emissions you need to remember the CO2 emissions from the power station unless you buy green electricity.

Electricity is very expensive however, which makes it a last resort for most people.

Heat Exchangers

Air conditioning units are heat exchangers and can be used to heat the air as well as to cool it. These work out less expensive than you might think and can produce warm air just for the cost of running the pump and fan in the unit.

Solar Cells

Solar hot water heating will not produce water that is hot enough to heat your house, though it will give you warm water (not hot) from your hot tap. This can be used as a pre-heating system that reduces the amount of gas, oil or wood you need to burn.

In Summary

Replacing your old gas boiler is only part of any solution to high heating bills. In England the government’s heating allowance can be used towards a replacement boiler, reducing the cost substantially. Insulation and lower room temperatures are the other two components of any solution. The days of heating your whole house to 220C are gone and we all need to adapt.
