Built-in components makes installation quicker and neater. Regular Gas Boilers Regular boilers sometimes known as conventional or heat only boilers are ideally suited to homes that already have a traditional central heating and hot water system which is linked to a separate hot water cylinder. Perfect for homes where a lot of hot water is used at the same time.
Ideal where there are two or more bathrooms. A good option in areas where water pressure is low. Compatible with solar water heating systems for a lower carbon footprint and lower energy costs.

They are very important to do regularly Read More ». Your boiler plays a central role in your home and not having an annual service can impact its performance, make your home unsafe and increase Dewar Gas Services were called by the client to inspect a leaking heat pump.
Upon inspection, we found that it was poorly installed by the The gas boilers of today are easy on the wallet, relatively easy on the environment and very reliable. In saying that, they may still need One question that comes up time and time again for us here at DeWAR Gas Service is how long it will take to replace a As we know, winter is coming, bringing with it cold weather, wind and rain.
A lot of people like to turn on their boiler around The benefits of a conventional boiler system include:. Faster hot water flow rate than combination boilers so you can run more than one hot water tap at any time. Also, if you have several bathrooms or showers or even a power shower then you can specify a larger capacity hot water cylinder and pump. Conventional boilers will need space for the water cylinder which is usually an airing cupboard.
This provides a great space for drying clothes. Water heating does not rely on the boiler alone but can be heated using the independent electric immersion heater, so great as a backup. Using the immersion heater for long periods will be costly though. Conventional boilers are also ideal if your mains water pressure is low as the system has its own hot water tank and pump.
However, you should also consider the negatives associated with conventional boilers:. Hot water heating is not instant so you will have to plan in advance or set the timer if you need to use hot water. The amount of hot water you have is limited to the size of the hot water storage cylinder. Once this is emptied you will have to wait for the cold water to reheat.
Non-Condensing All boilers are either condensing or non-condensing. A condensing boiler concentrates water vapor produced in the heating process, and uses waste heat to preheat cold water entering the boiler. Condensing boilers are extremely energy efficient because they can provide ample heat while operating at lower temperatures.
Non-condensing boilers typically operate at higher temperatures, and some heat ends up being vented outside. Non-condensing boilers are 80 percent to 88 percent efficient, while condensing boilers have efficiencies greater than 88 percent. Sealed Combustion vs. Non-Sealed Combustion Boilers are either sealed-combustion or non-sealed combustion units.
You should buy one that is sealed combustion because it brings outside air into the burner and directs exhaust gases outside. Non-sealed combustion boilers draw heated air in and then send it up the chimney, wasting the energy used to heat the air. Climate If you live you in a cold climate, a boiler may be a good choice for your home. But if you live in a warm climate, you may not need a central heating system.
In that case, consider a heat pump, which can satisfy your air conditioning needs as well as moderate heating requirements. Fuel Type Gas-fueled boilers may cost less to operate than oil-fueled ones if heating oil prices are high. Boilers are rated with an annual fuel-utilization-efficiency AFUE score, which tells you how much energy is being converted into useable heat.
New boilers must have an AFUE rating of at last 80 percent, and high-efficiency models are 90 to The higher the rating, the higher the equipment cost, but the lower the operating cost. Programmable thermostats can save you 10 percent annually on your heating bills. Boilers should be serviced annually by a heating professional to ensure efficient heating.
