Location – The location of your existing gas boiler may impact the costings, this is particulary true if you current gas boiler is located on an internal wall of floor with no direct access to the outside for flue termination. If you current boiler is located in the attic space the flue ( boiler exhaust) may be terminatingh at roof level increasing installation costs.

Gas Pipe Size -  The current gas pipe may be undersized and may need upgrading

Condesate Disposal – Your new gas boiler will require a nearby drain for the safe disposal of the condesate by product. If a drain pipe is not accessible you may need a purpose provided soakaway installed or condensate pump.

Electrical Controls -  If you require new heating controls, these additional measures will increase the installation costs

The above costings are estimates only and are for guidance only, additional factors may impact on costings.

If you are considering replacing your existing gas boiler and hot water cylinder with a combination boiler important consideration must be made to the following.

  • Gas Pipe Size -  If your current gas boiler KW is below 24KW you may need to upgrade your gas line. A combination boiler heats the water instantly on demand, this instant heat up of domestic hot water requires quite a large amount of energy. Therefore depending on the current gas pipe size, proximity to the gas meter and current gas appliances being served. You may need to upgrade your gas supply pipe to meet the additional energy demands.
  • Removal of Hot Water Cylinder -  With a combination gas boiler, there is no need for a stored hot water cylinder. Although the removal of your current hot water cylinder is straight forward, the piping will need to be altered to accept the system arrangement. The hot pipe will need to be redirected from the current cylinder location to the combi boiler.
  • Flow Rate -  Combination boilers are fantastic for smaller homes and families, the larger the hot water demand the less likely a combination boiler is the right choice for your home. Combi boilers typically produce between 10 - 15 litres of water per min at 40 degrees Celsius. Although this may seem quite acceptable, this can quickly become inadequate during peak times (ie morning showers).
  • Incoming Mains Pressure - Combination boilers require a minimum incoming water pressure/flow rate to operate. More often than not a pump will be required to meet the minumum pressure and flow rates.
  • Electric Showers - If you are current shower is electric, it may be worth while considering changing to a mixer shower.
