Boiler replacement options
Combi (Combination) boilers
The “combi” or combination boiler is a popular choice for many modern households, particularly those where space is at a premium.
How they work: A combi boiler is a high-efficiency water heater and a central heating boiler combined in a single compact unit. It heats water directly from the mains when you turn on a tap, so you don’t need a hot water storage cylinder or a cold-water storage tank in the roof space. These are some of the advantages offered by a combi boiler.
- Space-saving: Because there are no external tanks, they are fantastic for smaller homes or apartments where finding space for a hot water cylinder is difficult.
- Instant hot water: You get hot water on demand. There’s no waiting for a tank to heat up.
- Efficiency: Heating water only when you need it can be very cost-effective and energy efficient.
- Lower installation costs: With fewer parts and pipes to install, the initial setup is often cheaper than other systems.
However, keep in mind that water pressure might drop if you try to run multiple showers or taps at the same time. If you have a large family with high water usage during peak hours, this might be a limitation.
System boilers
If your home has a high demand for hot water—think multiple bathrooms being used simultaneously—a system boiler might be the comprehensive solution you need.
How they work: System boilers require a cylinder for storing hot water. However, the major heating and pump components are built into the boiler itself, meaning it can be installed more quickly and neatly than a regular boiler. Crucially, it doesn’t need a cold-water tank in the loft, freeing up that space. Here are some of the benefits of a system boiler.
- Great for busy homes: Since hot water is stored in a cylinder, multiple taps can flow at high pressure at the same time without a drop in performance.
- Faster installation: Many of the individual components of the heating and hot water system are built into the boiler, making installation easier than a regular boiler.
- Compatible with solar: Because they use a hot water cylinder, system boilers are often compatible with solar thermal systems, allowing you to boost your home’s sustainability.
Regular (Heat-Only/Conventional) Boilers
Also known as “traditional” or “conventional” boilers, these are often found in older properties. If you live in a classic New England home in the Greater Concord area, this might be what you currently have.
How they work: A regular boiler system is made up of a boiler, a separate hot water cylinder (usually in an airing cupboard), and a large cold water storage tank (usually in the loft). The boiler heats the water, which is then stored until needed. These are some reasons to choose a regular boiler
- Ideal for older systems: If your home has an older radiator system that might not cope with the high water pressure of a combi or system boiler, a regular boiler is often the safest bet.
- High volume: Like system boilers, these are excellent for homes where a lot of hot water is used at once.
- Easy replacement: If you already have this setup, replacing the boiler with a new regular model is usually more straightforward and cost-effective than changing the entire pipework infrastructure to accommodate a combi or system boiler.
We know that navigating these options can feel complex. Consulting with the experts at Johnny Prescott can help clarify exactly which system aligns with your renovation goals and budget.
Boiler replacement FAQs
Q. How do I know if my boiler needs to be replaced?
A. Common signs that your boiler may need replacement include:
- Frequent breakdowns
- Rising energy bills
- Strange noises such as banging or rumbling
- Inability to heat home effectively
If your boiler is over 15 years old, it may also lack efficiency compared to newer models. Also, if repairing your boiler costs 50% or more of the cost of a new boiler, replacing it tends to be the better choice in the long run.
Q. How long does a boiler replacement take?
A. Typically, replacing a standard boiler can take one to two days, depending on the complexity of the installation. This includes removing the old boiler, making any necessary adjustments to your system, and installing and testing the new boiler.
Q. How much does a new boiler replacement cost?
A. The cost of a boiler replacement varies depending on the type and brand of boiler, as well as installation fees. Johnny Prescott offers zero-obligation estimates free of charge.
