What is the Worcester Bosch Greenstar System Boiler?

the Worcester Bosch Greenstar System Boiler 24i is one of a range of highly energy-efficient A-rated gas boilers. They are rated very highly by SEDBUK 2009. Being a system boiler, the Worcester-Bosch Greenstar 24i System requires a hot water storage cylinder; however, it doesn’t require a feed and expansion cistern. This makes the Greenstar 24i a quick and easy boiler installation as well as being efficient and economical to run. What do we love about this system boiler?

With the Worcester-Bosch Greenstar 24i, heat from exhaust gases, that would otherwise be lost through the flue, are recycled. This heat is then used as output, powering your domestic hot water and central heating with what otherwise be wasted energy. This means that the Greenstar 24i is up to 30% cheaper to run than some older boilers. We rate this boiler lower than the Viessmann because the Viessmann has a much better stainless steel heat exchanger with better reliability than the Worcester Bosch. 

The price comes in around £1,050 on average with an installed price being around £2000.

Can I finance my new boiler?

What does it cost?

Firstly, a boiler replacement can cost a huge amount of money. It can cost you between £1,500 to £3,000. It’s perfectly understandable if you don’t have that amount on hand right now.

But worry not! You can easily get a monthly finance plan to pay for your new boiler. This plan will enable you to spread the cost over a period of time that is suitable for your budget. Moreover, you can pay for it in 2 years, 5 years or even in a decade. The choice is yours. And here lies the beauty of boiler finance.

Who can apply for boiler finance?

If you are over the age of 18, then you can easily apply for a new boiler pay monthly plan.

Besides the minimum age for boiler finance applications, there is a maximum age as well. Boiler finance lenders have a policy that won’t allow you to exceed 85 by the end of your finance agreement.

Being a UK resident for at least 3 years is also important for your application. What is equally important is having some way of earning your living. You will be approved if you are employed, on benefits or have an allowance.

If you are planning to apply for a finance plan, then you might need to provide some form of documentation. These might include:

• A valid UK passport or a driving license
• A utility bill dated the last 3 months of the boiler finance application date.

Check out Boiler Finance page to know more about the plan that we provide.

What is meant by a Condensing Boilers?

The terms condensing and non-condensing can be confusing to people shopping for a new boiler.

Presently, it is stated by law that new boilers must use condensing technology. In short, you don’t have to worry about getting a condensing boiler.

Condensing is not a type of boiler, but rather technical feature. In a Condensing boiler you get a much bigger heat exchanger. They also produce additional heat from the fuel. The same fuel that would have been wasted in a non- Condensing boiler. As a result, they are more efficient.

non-condensing boilers are less efficient by 50% since a lot of heat was lost in the combustion exhaust gases. On the other hand, new boilers would capture this heat and use it to heat water.

condensing boilers are energy efficient by 90%. They use excess energy to heat your property. Not to mention, they are environmentally friendly and reduce your heating bill.

Can I get the next-day boiler installation?
