Make a Solar Water Heater

Do you believe that solar power is a wonderful way to get free hot water in your home?  You can make and fit diy solar water heating easily and cheaply, perhaps for under 100 dollars depending on the materials you have available.  Commercial solar water heaters can cost over 1,000 dollars so making a solar water heater yourself will save you hundreds of dollars, repaying its cost in one or two months.  And think of the savings every month after that!

Solar heating works anywhere and at any time of the year – even wintertime!  It is possible that solar heat might not provide all your hot water (it often does), but it will definitely save you a large chunk of your utility bill.  At least one third is quite common.  These systems are simple, effective and very eco-friendly.  Making a solar water heater is easily a weekend project, provided you plan the job in advanceand get all the parts assembled.

A typical solar water heater system simply includes a collector box with integral water pipes that are connected to the existing domestic hot and cold water pipes near your hot water cylinder.  Normally a drain valve is fitted should you need to empty the system for some reason, such as going away for a winter vacation.  Plumbing is easy and no special skills or tools are needed.  Position the collector box so that it faces the mid-day sun, mounting it on the roof if you wish, or attached to a wall, but ideally close to your hot water tank to minimize heat losses through the pipes.  All necessary materials will be available from your local hardware store, although you will probably find you already have some of them in your shed.

You will not damage your existing hot water system when making and fitting a solar water heater.  In fact, by lowering the use of the existing heaters, the solar hot water heater will help prolong the life of your boiler or immersion heater as well as save on utility bills.  Remember also that solar heating is free energy that reduces our use of non-renewable fuels and lowers the carbon footprint, so there is an eco-bonus for fitting a solar water heater as well.

It also has other uses.  Solar hot water systems can help heat a swimming pool with constant, gentle heat all year.  Do you have, or are you planning on fitting, underfloor central heating?  This typically operates on a constant supply of warm (as opposed to hot) water with a low flow rate. A diy solar water heating system is an ideal way of getting free heat in your house.

There is something very satisfying about making a simple device that saves you money, gives you free hot water on demand and helps save the planet at the same time.

But, as always, there are pitfalls for the inexperienced when trying to make and fit a solar water heater.  It makes a lot of sense to get expert guidance and advice at the planning stage and before you start to build.  The cost will be very small, and you will get full assurance that you are doing the job properly and safely. You will find out more about this on our specialized website.

In conclusion, we know from experience that making and fitting a solar water heating system will give you immense satisfaction, a lot of fun and really significant savings, so why not give it a try?
