Vaillant Cost and Fees

Vaillant, like many boiler manufacturers, doesn’t offer any specific information regarding the prices of their boilers or their other products, because the costs will be down to the discretion of the sellers like Wickes for example.

Here are some of the prices you can see on shop websites:

  • Vaillant Ecofit Pure 830 Combination Boiler: £1,100

You can use these figures as a general guide to finding the best cost-effective solution for you, as it is likely that you will find slightly different prices depending on where you look.

Vaillant Core Services

Combination Boilers

Combination boilers do two things; heat water and your central heating system.

This is why they are ideal for smaller homes because they don’t take up a lot of space, they don’t require anything like a hot water tank or cylinders.

It heats your water as and when you need it, which is why it heats the mains water that comes out of your taps as and when you require hot water, rather than heating it before.

✔ Excellent performance

System Boilers

System boilers require a hot water cylinder to ensure that you can get instant hot water, as it will be stored in the tank that is often in your loft.

These boilers might be best suited for homes that have more than one bathroom, which requires hot water in multiple places at once.

✔ Top performance and efficiency
