A radiated heating system is incomplete without a boiler. It is responsible for producing hot water and sending steam (or hot water) to radiators. The radiators will distribute heat through your entire house. Buy a boiler after determining the needs of your home. It is necessary to decrease your energy bills. Selection of a boiler is not easy because the market has several options.
After purchasing a boiler, you should get suitable insurance for your unit. With Corgi Home Plan, you will get boiler and heating breakdown insurance, annual boiler services, unlimited callouts for repairs and breakdowns. A reliable insurance plan can decrease your stress for breakdown and repair of the boiler. Here are some tips that will help you to buy the right boiler.
Steam or Hot Water
You can get a boiler for hot water or steam applications. Before selecting a boiler, you have to determine your domestic needs. In case of confusion, get professional advice to choose the right boiler. Some clues may help you to choose between hot water and steam boiler.
In the first step, you have to check your radiators. Carefully determine if they are panel radiators, cast iron or baseboard radiators with an air vent. These are suitable for the steam system to let air escape and welcome steam in the radiator with the initial stats up of the system.
Check the number of pipes connected to a radiator. Systems with a single connection to the radiator are always steam. A system with two-pipes could be hot water or steam. With a radiant floor heat in a home, you must have a system for hot water.
Even after checking the radiator, you can’t determine the type of system; you have to inspect your boiler. A system with a small glass tube (a sight glass) is a steam-fired boiler. The glass is mounted toward the side of the boiler. With sight glass, you can see the level of water in the boiler.
Sight glasses are not available in hot water systems. In these boilers, you can see other installed accessories, such as the expansion tank or pump. A circulator pump is not available in some old systems of hot water. In these systems, you can find expansion tanks in the loft. In case of any confusion, call experts for your assistance.
You can power your boiler with different fuel options, such as electric, fuel oil, LP (liquid propane) and natural gas.
- Natural Gas: You can get this fuel easily in urban zones. If you are getting gas from the main utility, you can buy a natural gas boiler. You will get monthly bills for the total usage of natural gas.
- Propane: If you don’t have a supply of natural gas in your area, you can prefer propane as a fuel source. Propane is stored in tanks located on a property where they will be used. The reservoir may be located underground or above the ground. Propane will be required almost 3 to 4 times annually. Feel free to convert some natural gas boilers to propane with a conversion kit.
- Fuel Oil: In the unavailability of natural gas, you can get oil as a fuel. Along with propane, you can see a tank on the property. Arrange periodic deliveries of fuel for this tank. Biomass, coal, and wood are available to fuel options in rural areas. You have to load these boilers for heating operations manually.
- Electric: If any type of fuel is unavailable in your area or excessively expensive, you can choose electric boilers. These boilers are suitable to handle small applications like add heat to your garage.
Check Venting Options
A boiler must have a system to decrease combustion gases produced after burning fuel. The main types of vents available in a boiler are direct exhaust (power venting), sealed combustion (direct venting), and chimney. You have to select a perfect option for your home based on your current boiler, construction of a house and desired efficiency from a new boiler.
Boilers with chimney vent may reject combustion gases via one vertical chimney. Every boiler may have specific height, construction, and size of chimney. Only a professional can determine whether a chimney venting is suitable for you. This venting system depends on a principle that hot air is less in density than fresh air, so it is naturally buoyant.
The buoyant, hot air can travel upward in the chimney and pull fresh air for successful combustion. This passive procedure doesn’t involve motor force to push hot air out. Insufficient supply of fresh air and obstruction in the chimney can affect this operation. Instead of selecting a wrong boiler, you are advised to call experts for their assistance.
