Back Boiler Engineers In London, Back Boiler Specialists
Back boilers can be fuelled by gas, oil or solid fuel. All require a lined, natural-draught open flue to expel the potentially harmful gases. Solid fuel back boilers can only provide hot water when the fire which heats the house is lit. Gas and oil back boilers however can work independently of the fire front so are able to provide hot water all year round. An electric immersion heater can be used as with a conventional boiler.
Back Boilers Units used to vastly occupy the boiler market years ago, but as time has moved on, the Back Boiler Unit became increasingly rare, being replaced by more modern wall hung boilers, creating more space and flexible siting within the household.
Back Boilers however are making a comeback. Baxi in particular have re-modelled their older Baxi Bermuda Back Boiler, which was first launched on the market in 1966. Now the Baxi Bermuda BBU Back Boiler Unit is a condensing boiler, making it fully compliant with current regulations, and highly efficient.
The Baxi Bermuda BBU Back Boiler is the only available Back Boiler Unit on the market today, making it a simple and easy direct replacement for an older back boiler unit, without the need to totally re-site the boiler, re-locate pipework, and redecorate entire walls.
Baxi Bermuda BBU Back Boiler can be installed with specially manufactured BBU Fires from Valor. A vast range of Valor Fire Fronts are available to purchase, so you can not only update your central heating/hot water system to a high efficient one, you can also modernise your decor with a new Valor Fire Front and surrond, such as the Valor Dimension or Valor Dream, if you want a more traditional image.
Get to know How Combiation Boilers Work
Combination or combi boilers, combine the central heating (CH) with (tankless) domestic hot water (DHW) in one box. They are not merely infinitely continuous water heaters having the ability to heat a hydronic heating system in a large house. When DHW is run off, the combi stops pumping water to the hydronic circuit and diverts all the boiler's power to instantly heating DHW. Some combis have small internal water storage vessels combining the energy of the stored water and the gas or oil burner to give faster DHW at the taps or increase the DHW flowrate.
Combi boilers are rated by the DHW flowrate. The kW ratings for domestic units are 24 kW to 54 kW, giving approximate flowrates of 9 to 23 litres (2.4 to 6.1 US gal) per minute. There are larger commercial units available. High flowrate models will simultaneously supply two showers.
A further advantage is that more than one combi unit may be used to supply separate heating zones, giving greater time and temperature control, and multiple bathrooms. An example is one combi supplying the downstairs heating system and another the upstairs. One unit may supply one bathroom and one another. Having two units gives backup in case one combi is down, provided the 2 systems are connected with valves that are normally closed.
Installation cost is significantly lower and less space is required as water tanks and associated pipes and controls are not required.
Combi boilers are highly popular in Europe, where in some countries market share is 70%.
Combination boilers have disadvantages. The water flow rate is likely to be less than from a storage cylinder, particularly in winter. The power rating needs to be matched to heating requirements; heating water ‘on demand’ improves energy efficiency but limits the volume of water available at any moment. The water supply pressure must not be too low. It has been proposed that a flow regulator valve can control the amount of water used. Additionally, a combination boiler has more moving parts that can break down, so can be less reliable than a tank system.
