Is it time to replace your old boiler with a new one?

Some older boiler models can last for many years with appropriate maintenance, but if you’re reading this, it’s probable that you’ll need a new boiler soon.

It’s sometimes necessary to bite the bullet because repair costs can quickly mount, especially if you don’t have a boiler protection plan.

Here are several signs that your boiler needs to be replaced:

  1. Your current boiler is beyond repair (BER). In these situations, getting a new boiler is frequently less expensive than getting it fixed. You’ll also save money on your heating expenses with the new boiler.
  2. Frequent faults that need having it serviced more than once a year or multiple call – outs suggest it’s becoming costly, and replacing it is the best solution.
  3. Energy efficiency – If your current boiler is expensive, it will cost you more gas in the long run. A new boiler would be the greatest option in this situation.
  4. If you are selling or renting your home, installing a new boiler can raise the value of your home. If you rent it out, your tenants will appreciate the lower energy expenditures. A new boiler will usually increase the value of your home.
  5. Your boiler is dripping – If leaks are costing you money in call outs, an expensive boiler may be the best long-term replacement for you.
  6. Moving the system – If you want to relocate your existing boiler, it’s usually best to get a new boiler instead. Upgrading your heating system would be less of a hassle and usually the best solution.

If you’re having any of these significant problems, it could be time to retire your old boiler and replace it with a new one.

How to get the most suitable new boiler for your home

The type of new boiler that is suitable for your home is entirely reliant on it. A little Dublin flat with one bedroom, for example, would require a different replacement boiler than a five-bedroom property in Mayfair.

We’ve compiled a list of the most important characteristics to look for when replacing a combi or gas boiler.

1- Use of hot water:

A conventional boiler will be more efficient for large families who consume a lot of hot water. A combi boiler is ideal for a home with fewer residents.

2- Size of the house:

We can install combi boilers in a home with less space because they don’t require hot water cylinders. Depending on the size of your home, see our recommended replacement boiler size table.

3- Compatibility with solar water heating:

If you use solar to heat your water, you should be aware that many combi boilers are incompatible and inefficient with this type of heating system. If you have any questions, please contact us. Many antique gas and oil boilers are nothing more than boilers with hot water cylinders in the airing closet and cold water tanks in the loft.

When replacing a normal boiler or a system boiler, the hot water cylinder should be able to stay with the new boiler installation.

In the United Kingdom, combi boilers are the most prevalent. Combi boilers, sometimes known as ‘combination boilers,’ are a single-unit system that fits within a kitchen cabinet.

A combi boiler is ideal unless you have a large demand for water from many taps at the same time. In this scenario, a normal boiler would be preferable.

Replacing out a certain boiler type

Replacement of a gas boiler on a regular basis

Heat-only boilers, often known as ordinary boilers, are traditional systems.

Hot water is stored in a cylinder, while cold water is stored in a storage tank in these variants.

Regular boilers produce hot water more effectively than combi boilers and can simultaneously supply water to several taps.

The feed and expansion tanks, as well as the circulation pump, are housed as exterior components.

There is usually an on/off switch on these. This allows you to heat the water in the storage tank ahead of time when you know you’ll need it. When it’s not in use, you’ll save electricity.

Pros:

  • Large homes benefit from traditional boilers.
  • Multiple taps can be supplied with a large amount of hot water at the same time.

Cons:

  • It can be difficult to replace a traditional boiler with a combi boiler.

The most common type of residential boiler system registered in Dublin is combination boilers, commonly known as combi boilers.

They provide rapid hot water as well as effective Kildare Plumbing and Heating.

When you ask for hot water, a sensor tells the boiler to start burning gas, electricity, or oil.

Pros:

  • External components are not required for gas combi boilers, making them appear sleek and compact.
  • Without the need of cold water or a feed and expansion tank, hot water is provided on demand.
  • They are less expensive to install than standard models.

Cons:

  • There are more internal moving parts, which means there are more possible failures. Repairing these faults may be more costly than with a traditional boiler.
  • A combi boiler system can only supply hot water to one user at a time. Combi boilers are less suitable for larger homes because of this.

Replacement of a system gas boiler

Closed vent boilers are sometimes called as system boilers.

If you prefer a heat-only boiler with fewer external components, they are ideal.

External components are built into the body of the heating system, similar to a combi boiler.

A hot water cylinder is included in system boilers, but the feed and expansion tanks are supplemented by an expansion vessel in the new boiler.

The circulation pump and valves are housed in this compartment.

Pros:

  • System boilers are ideal for large households where warm water is required for multiple tasks at the same time.
  • They don’t take up the same amount of room as a traditional new boiler.
  • In places with low water pressure, system boilers are extremely efficient.

Cons:

  • They’ll need somewhere to store the heated water cylinder.
  • The cost of installation is higher than with standard combi systems.
  • They are less efficient than combi systems because they lose heat from the hot water cylinder’s stored water.
  • After the hot water has drained from the cylinder, one must wait for it to heat up again.
