Frequently asked questions
What is required when swicthing from a non-condensing to a condensing boiler?
When switching from a non-condensing to a condensing boiler some additional pipework is required:
- During combustion, condensed water accumulates. You will need a drain connection to drain the condensed water.
Your installer will advise you on these modifications and carry them out when replacing your heating system.
Does a gas-fired condensing system work with both radiators and underfloor heating?
Yes, a gas-fired condensing system works with all heat distributing systems such as underfloor heating and radiators. However, the lower the flow temperature of your heating water, the more you will benefit of the condensing effect. Thus, the biggest savings will be possible with an underfloor heating system.
Are there any legal requirements that I need to consider?
The legislation, Boiler Plus means that from April 2018, all boilers must have a minimum ErP efficiency of 92% and all installations must have time and temperature controls fitted, if they aren't already present and working correctly.
Can I improve the efficiency of my current heating system without replacing it?
Yes you can. Whether you choose to replace your heating system or not, you should follow the next few steps to help improve the efficiency of your heating system:
- Bleed your radiators to ensure an even distribution of heat inside the radiators. For advice on how to bleed your radiators, please see our How to bleed a radiator page.
- Have your boiler serviced annually
