Ravenheat WH System 4-24 Gas Boiler Pros and Cons
Building on its impressive performance metrics, let's weigh what makes this Ravenheat model shine – and where it might fall short.
You'll appreciate the boiler's stellar 90.4% efficiency rating and A-rating for energy performance – your utility bills will thank you. The 5-year warranty offers solid peace of mind, while the compact design won't eat up valuable space in your utility room.
However, there are some trade-offs to reflect upon. With an output range of 4-26.2 kW, it's not ideal if you've got a larger home.
You'll also need to factor in the higher upfront cost, typically around £579 for the unit alone. Plus, you'll want to budget for installation, which can add £500-£1000 to your total investment.
How Does The Ravenheat WH System 4-24 Gas Boiler Compare To Similar Models From Other Manufacturers?
When stacking up against similar models from leading manufacturers, the Ravenheat WH System 4-24 holds its own as a budget-friendly contender.
You'll notice it's priced £400-500 lower than comparable models from Vaillant, Worcester Bosch, and Ideal.
However, there are some trade-offs to evaluate. The Ravenheat's 90.40% efficiency rating falls a bit short of competitors who achieve 93-94%, which might impact your energy bills over time.
You're also looking at a shorter warranty – 5 years compared to 7-10 years from other brands.
If you're watching your budget and need a reliable system boiler for a smaller home, the Ravenheat is worth assessing.
But if you're planning to stay put long-term, you might want to invest in a higher-efficiency model from one of the more established brands.
Our website offers detailed boiler comparisons to help you make an informed decision between different manufacturers.
How Much Does A Ravenheat WH System 4-24 Gas Boiler Cost?
Speaking of comparing costs, let's look at the actual numbers for the Ravenheat WH System 4-24.
You're looking at £579 for the boiler unit itself, which includes VAT – not too shabby for a quality system boiler.
But here's where you'll need to dig a bit deeper into your wallet: installation costs typically run between £500-£1,000, and you'll need around £300 for essentials like the filter and flue.
All in, you're looking at a total between £1,379 and £1,879.
Word to the wise: if someone quotes you under £1,000 for a full installation, that should raise some eyebrows.
The good news? You'll get a 5-year warranty included in the price, and the 90.4% energy efficiency rating means you'll save on those heating bills.
