Is the Bosch Highflow 21e right for me?

When considering purchasing a new hot water heater you need to take many factors into play to ensure you get the right system to suit your property and your hot water requirements.

You need to look at the size of your property, how many residents along with how you all use your hot water e.g. how many showers in a day, do you use the bath, how often you wash the dishes or if you use a dishwasher and if you wash clothes using hot water etc. to ensure the unit you choose has the capacity to suit.

You also need to know which fuel sources would be the best option for your home or office – do you have access to natural gas, can you install solar panels on your roof facing the right direction? etc.

As you can see there is so much to consider rather than just the price of a hot water system.

Choosing a system based solely on price is never recommended as you may end up paying more going forward on your energy bills, or end up with more cold showers than you’d bargained for!

If you want to take the hassle out of your research call Jim’s Plumbing.

We’ll send a fully qualified and insured hot water heater specialist to your location to provide you with a no obligation quote to supply and install the ideal hot water heater for you.
