Combi Boiler Installation FAQs
Q: What is the difference between a combi boiler and a conventional boiler?
A: A combi boiler provides heating and hot water directly from one compact unit without a separate water tank. Conventional systems typically use tanks and cylinders for stored hot water.
Q: Which boiler size is right for my home?
A: The right boiler size depends on factors including the number of bedrooms, bathrooms, radiators, and hot water usage in your property.
Q: How long does a new boiler installation take?
A: A straightforward replacement may take one day, while changing boiler type or relocating the system can take longer.
Q: How much does a new gas boiler installation cost?
A: Costs vary depending on boiler type, size, installation complexity, and any additional work required such as pipework upgrades.
Q: Will a new boiler reduce my energy bills?
A: Modern energy-efficient boilers can help reduce fuel consumption and improve heating performance, particularly if replacing an older system. Energy-efficient systems are commonly recommended for reducing running costs.
Q: Do new boilers come with a warranty?
A: Most new boilers include manufacturer warranties, with coverage periods varying by model and installation requirements. Annual servicing is often required to maintain warranty validity.
Q: Do I need an annual boiler service after installation?
A: Yes. Annual servicing helps maintain efficiency, supports safe operation, identifies potential issues early, and may be necessary to keep manufacturer warranties valid.
Q: Why should I choose a Gas Safe registered engineer?
A: Gas appliances should only be installed or repaired by qualified engineers registered to work safely with gas systems.
