The great price war: electricity vs water

This is a guest blog from Tim Sparke at with some good advice about pump selection.

When it comes to making sure that your home has access to a reliable water supply, there are two factors to consider. The first is how much water your home is going to need (ATA Tankulator is a good start). The second is how much electricity you can expect to burn through. The latter is important to both our beautiful natural environment, and your wallet!

So, when it comes to choosing the right pump for your home, you should think about both of these issues. Unfortunately, many people think that the only way of guaranteeing water is by buying the largest, most powerful pump they can get their hands on. But this just isn’t the case.

It’s a far better idea to start off by figuring out exactly how much water you’ll need. One easy way to think about it is to calculate how much water your house might go through in a minute. For example, if you have a tap, washing machine and toilet running at the same time, they’ll use about 30 litres per minute on average (if you’re wondering, the tap uses 12 litres, the washing machine 9 and the toilet 6). So you only need a pump that can take care of this level of flow. You don’t need one that’s made to handle 200 litres per minute – unless you turn your house into an international hotel, you’re never going to need that much power, so why pay for it?

By opting for an appropriately-sized pump, rather than an enormous one, you can rest assured that you’ll have a constant, reliable water supply, as well as maximum savings on your electricity bill. There’s a win on both fronts! When trying to decide how much water flow you’ll need for your particular home, it can be a good idea to consult an expert. Pumps are expensive items, so guessing incorrectly can be a rather expensive mistake.

To save even more cash and energy, it’s also worth considering an accumulator tank. An accumulator tank holds a residual volume of water. So when you fill a glass of water or flush the toilet the pump doesn’t need to start every time. This reduces pump starts resulting in less electricity wastage, lower power bills and even helps extend the life of the pump. With all types and sizes you can fit them into almost any pressure pump system.
