3 Important Things to Keep in Mind When Looking for Boilers

Choose the boiler that fits your needs

Looking for boilers

With a variety of options to choose from, getting the right boiler for your home might prove a puzzling task. Therefore, before buying a boiler, you have to check thoroughly all the available information about boilers. It is important to take into account your household needs in terms of how much heating capacity it is required in order to ensure a comfortable environment for everyday life. In so doing, you’ll be able to pick up the boiler that will entirely meet these needs. It is equally important to consult with sales and installation specialists before purchasing a boiler appliance.

Floor Standing or Wall Mounted Boiler?

Most of the modern boilers intended for single-family homes are designed to be mounted into walls. Exceptions exist for boilers that come with integrated high volume pressure tanks, as well as for boilers with high electric power capacity (more than 30 kW), although small power boilers can also be designed as floor standing.

Floor Standing Boilers

Typically, a floor standing boiler (also known as a free standing boiler or a floor mounted boiler) is a more advanced version of a wall mounted boiler, in terms of the heating capacity it has to offer and its electric power consumption rates. If the boiler capacity exceeds the 100 litres limit, then its size and weight make it impossible for hanging the boiler on the wall. Its superiority over the wall mounted boiler is subject to its ability to provide large quantities of hot water, since it has an integrated high capacity water heater. A ‘floor boiler’ usually resembles a refrigerator, in that the shape and size look similar and thus, it can be easily installed in a specially designed closet, boiler or workshop room. A system like this would not ruin your room’s decor, whereas most of the connecting pipes and fittings are hidden under one big case.

Wall Mounted Boilers

The immediate benefits of these boilers are their small size and price. Even if it looks like a small hinged cupboard, it is a fully staffed boiler system, equipped with an expansion tank, safety valve, and a water circulation pump. Thus, a wall mounted boiler would perfectly fit in a small house or apartment in which there is no place for the installation of a larger equipment.

Conventional or Condensing Boilers?

By burning fuel, conventional boilers cannot take full advantage of the energy capacity a fossil fuel like gas or oil has to offer. A significant amount of heat, dubbed ‘latent heat’, is being wasted along with the water vapour that is pushed up the chimney together with combustion products. In order to use the boiler’s ‘latent heat’, it is necessary to trigger the process of water vapour condensation, by cooling down the exhaust gases. Only condensing boilers are capable of achieving the required level of condensation that will result in additional heating capacity being generated. Thus, the efficiency rate of a condensing boiler is about 10-11% higher, compared to the one of conventional boilers. Consequently, condensing boilers consume less fuel for producing heat, and therefore, will make the heating of your house significantly cheaper.

Boilers with Manual or Automatic Control?

Gas boilers require little maintenance. After mounting and installing the required fittings, both single- and double-circuit, conventional and condensing boilers, can be operated without direct human involvement.

According to the Ofgem’s regulatory framework, before the onset of the next heating season, boilers should be subjected to a thorough verification process conducted by a certified specialist. During inspection, the boiler and its elements are cleaned and tested for proper functioning. The gas exhausting system and the boiler chimney are checked and cleaned as well.

For operating a boiler in a cost efficient and comfortable manner, a temperature controller is required. The most common method for adjusting the work of a boiler is using a mechanical thermostat. Its immediate role will be to constantly monitor the room's temperature levels, based on which it will turn on or turn off the boiler until the owner’s desired temperature levels are reached.

Still, for people who are looking to obtain greater flexibility and autonomy when operating a boiler, a self-programmed thermostat with a number of boiler management functions will better serve this goal. It will automatically set the temperature levels according to the time of the day, taking into account the homeowner’s heating preferences.

A more precise temperature control is provided by the weather thermostats, that have an integrated outdoor temperature sensor. Depending on the outside weather conditions, these thermostats adjust the boiler’s coolant temperature. In doing so, the thermostats are able to sustain the highest efficiency rate and deliver a cost efficient boiler operation.
