Types of boiler
There are three basic types of boiler:
Conventional, Combination and System
A conventional boiler is the sort of boiler that comes with a water tank or cylinder where hot water is kept. Gallons of water can be heated or stored and then used later, this also means the hot water pressure will not reduce no matter how many taps are in use. A conventional boiler uses a cold-water feed, usually from a couple of tanks in the loft, to provide heat. Part of this heat is used to warm a separate tank of hot water, often found in an airing cupboard or elsewhere inside the house. The heated water is then stored for use when it is required. If this store of hot water runs out, you must wait for it to re-heat. They are also probably the bulkiest options for central heating.
A combination boiler delivers both hot water and heat on demand. In most cases there is no water tanks involved, thus meaning they are generally considered the most efficient option and more compact, which makes them the most popular. Maintaining good water pressure may be a problem however if more than one tap is used at once.
A system boiler (often also referred to as “a sealed system”) provides heat to your central heating system then heats up a tank of hot water too, just like a conventional boiler however, unlike a conventional boiler – the major components of the heating and hot water provision are built into the boiler this makes it slightly more efficient. The hot water is pumped around the radiators and to the hot water tank directly from the system boiler – this then makes it much more economical to run and renders the cold-water tank unnecessary again though, a hot water cylinder will still need to be stored and after one lot of hot water has been used, it may take time to heat up any more.
A fourth, modern type of boiler is the condensing boiler. Since 2003 many new boilers have been condensing. Condensing boilers are designed to be the most efficient, to make use of all the heat they produce rather than releasing any of the hot gases made up the flue. A condensing boiler traps these hot gasses, and ‘condenses’ them to extract the heat, which is then used in your heating system, this results in less gas usage. To work however, they do require a condensate pump and drainage pipe which cannot freeze, so insulation may be necessary. Not only are they more efficient and cost effective in long term running, they are also safer as there is less chance of carbon monoxide problems. Along with this they are arguably more reliable, most modern condensing boilers are fitted with a heat exchanger, this heat exchanger is constructed from stainless steel or another non-ferrous material. This means they won’t rust over time therefore, less chance of this affecting reliability and deteriorating performance. Condensing boilers can be up to 30% + more efficient and involve less fuel consumption. This means a lowered carbon footprint.
Choosing the right size of boiler is almost as imperative as the boiler type and brand. Selecting a boiler too small means you won’t have enough hot water for radiators and taps, oversizing your boiler means a massive inflation in up front costs and wasted fuel and money through mass inefficiency. Every home is unique and sizing your boiler is a complex calculation that one of our engineers would be happy to help you with! How much water do you use? How much space do you have? Do you have an ideal location you would like your boiler to be? Is your home well insulated already? How many radiators does your property have? How many people live in your property?
Considering solar power
If you are replacing a hot water cylinder, particularly if you are concerned about your carbon footprint, solar power might be a good idea! A twin-coil cylinder is connected to a solar panel that generates electricity. In summer, hot water will be probably be free, but it may need topping up in winter. The initial outlay is likely to be costly, but over time this will all be earned back.
Boiler installation and costs
The price of replacing a boiler along with installation of a new boiler, costs less than you might think; Aura Gas can supply and fit your new boiler starting from as little as £1,560, which also includes up to 12 years guarantee. And we also offer the option of spreading the cost with 0% APR, or ‘buy now pay later’ is also available. So, the flexibility in choice as well as boiler type and placement is endless! Aura Gas is happy to explain your options. We also have flexible service plans available to maintain your boiler with annual check-ups.
If it’s a straightforward swap for example, same location, size and boiler type but a newer mobile you can expect this to be completed within a day, if it’s a very aged boiler system, a different size location or you’re changing boiler type, there may be complications which prolong the installation. You may also require boiler flue or pipe upgrades. The cost can vary wildly dependent on your individual wants and needs.
