Frequently Asked Questions - Viessmann Appliance Repair St David's
What is a condensing boiler?
A condensing boiler captures heat from exhaust gases that would otherwise be lost, converting water vapour back into liquid around the heat exchanger. This process makes condensing boilers significantly more efficient than older non-condensing models, typically operating at around 90 per cent efficiency. Upgrading to a modern condensing boiler can reduce heating bills by up to 30 per cent.
How do I use my heat pump efficiently?
Heat pumps work best when maintaining a consistent temperature rather than making frequent adjustments. Avoid lowering the temperature at night, as this increases energy consumption when the system works to reheat your home. Use smart thermostat controls to set your desired temperature and let the system maintain it automatically.
How do I maintain my heat pump?
Regularly check the outdoor unit to ensure it is clear of debris such as leaves and is not frozen over. Ice buildup should trigger an automatic defrost cycle. For any issues with refrigerant, leaks, or continuous operation in summer, contact a qualified heat pump technician. Professional servicing should be carried out annually.
What should I do if I smell gas?
Do not wait for a boiler service. Make sure that you and your family are not in immediate danger, evacuate the building immediately, and call the Gas Emergency Service on 0800 111 999. Do not turn on any electrical switches or appliances.
Do heat pumps use a lot of electricity?
Heat pumps use electricity, but because of their high efficiency, they produce more heat energy than they consume in electricity. For an average home requiring 12,000 kWh of heat annually, a heat pump with a CoP of 3 would use approximately 4,000 kWh of electricity. Combining a heat pump with solar panels can reduce running costs by up to 40 per cent.
