Boiler Options: Find the Best Heating System for Your Home

If you’re thinking about a new boiler, you’ve probably heard terms like "combi", "system" and "condensing" thrown around. It can feel like a jargon maze, but the basics are simple. A good boiler keeps your house warm, provides hot water quickly, and doesn’t break the bank on bills. Below you’ll get a quick rundown of the main types, plus the key things to weigh before you decide.

Common Boiler Types

Combi boiler – The all‑in‑one unit. It heats water on demand, so you never need a bulky storage tank. Perfect for small‑to‑medium homes where space is tight. The downside is that if several taps run at once, the flow can dip.

System boiler – Works with a separate hot‑water cylinder. You still get a constant supply of hot water, even if multiple showers are running. Ideal for larger homes with multiple bathrooms. Installation is a bit more involved because of the tank.

Regular (or conventional) boiler – The old‑school setup with a boiler, cylinder, and a cold‑water tank in the loft. It’s reliable and works well with older heating systems, but it needs more space and is less efficient than newer models.

Condensing boiler – Not a separate type, but a technology that can be added to any of the above. It recovers heat from the exhaust gases, squeezing out extra efficiency. Look for an A‑rating for the best savings.

What to Look for When Choosing a Boiler

Size matters. A boiler that’s too small will struggle on cold days; too large and you waste fuel. Most installers use a heat‑load calculator that factors in room size, insulation and how many radiators you have.

Fuel type. Most UK homes run on gas, but oil, LPG and electric options exist. Gas is usually cheapest, but if you don’t have a mains supply, you’ll need an alternative.

Efficiency rating. The higher the rating, the less you’ll pay for heating. Modern condensing models often hit 90‑95% efficiency, which can cut bills noticeably.

Space and location. Combi units need a wall in the kitchen or utility room. System and regular boilers need space for tanks, so measure carefully before you choose.

Installation time and cost. A simple combi swap can be done in a day, while a system or regular boiler may take a couple of days because of extra pipework. Get a clear quote that includes the boiler, labor and any required parts.

Don’t forget maintenance. Regular servicing (once a year) keeps the boiler running efficiently and extends its life. Most boilers last 10‑15 years if looked after, but corrosion or wear can cut that short.

If you’re not sure whether to repair or replace, think about the age of your current unit, the cost of the fix, and how long you plan to stay in the house. A repair under £200 on a 12‑year‑old boiler might not be worth it; a new, efficient model could save you more in the long run.
