If you’ve just been shocked by your recent power bill, or your hot water system needs replacing, and you're now wondering whether a solar powered version might be the way to go?

Add to this the convenience of temperature controllers, which allow you to set your hot water to your desired temperature, on demand.

The usual warranty* period for a gas continuous system is : 10 years on the heat exchanger.

When a hot water system goes – with a bang, a whimper, or even a flood – it tends to go suddenly.

Instead, you get a replacement of the same type wheeled in ASAP – and try to forget about it until next time. But what if you were missing out on a better product?

Water heating accounts for a quarter of typical household energy use – and it can be even more. It's worth reviewing your hot water use well before your current system dies and then checking out the alternatives. You may find a hot water system (HWS) that saves energy and money and is kinder to the environment.

Also, regulations aimed at reducing energy consumption now mean a new electric storage system is not an option for many new homes.

The answer for this question is really in your hands only however we can help you better understand your future solution by further investigating into your demand requirements, such as :

  1. How many showers, kitchens and taps do you have?
  2. Has your current system been fulfilling your demand, throughout the year?
  3. Is your property single or multi levelled?
  4. Does your demand increase significantly during certain times, ie mornings?
  5. Are you more interested in a low cost solution for immediate savings or are you looking to invest in your hot water system to help the environment and to also reduce your medium to long term energy costs?

Gas hot water systems have energy efficiency star rating labels; the more stars, the more efficient the water heater. This is a voluntary rating scheme, unregulated by government. The highest rating is six stars.
