What to Look for In an On-Demand Water Pump?

When shopping for an on-demand water heater there are several things that you will want to consider.

Probably the first and most important thing to consider is the size.

In order to do this, you will need to determine the gallons per minute of hot water that you might use at any given time. This should include your washer, dishwashers, showers, tubs, and sinks.

Make the calculation like all the appliances will be running at the same time. This will ensure that you have enough hot water at all times. If you already have a water heater in the cabin you could simply go back with the same size if you aren’t currently having any problems with supply.

You will also have to decide whether you want an electric on demand water, a natural gas one, or a propane one.

Electric water heaters obviously have their advantages because they do not require the installation of any additional gas lines, but do not heater water as fast.

Another thing to consider with gas is that the pilot line will always be lit unless you opt for a model with an intermittent ignition device. These models turn the pilot light off and on based on the water demand.

Pump Care and Maintenance

If you want your on-demand water heater to last and perform at top levels, you are going to need to maintain it.

This might seem like a job for a professional and there are many out there that can do it, but with a little bit of knowledge, you can care for your own water heater.

At the end of the day, it doesn’t really matter who services and maintains your water heater as long as it is getting proper maintenance.

One of the most important maintenance tasks will be to regularly remove limescale.

Limescale usually builds up in the heating chamber of the unit and if left unattended for prolonged periods of time it can have serious impacts on the efficiency of the system. Left unattended long enough and you could potentially shorten the lifespan of your unit.

To begin removing limescale from the unit, you will want to shut off the power to the water heater and remove the cover. This usually just consists of a few screws and should be a simple start. Once the lid is removed, go ahead and close off the three water valves that supply the water to the water heater.

Now locate the purge valves. There should be one on the cold-water side as well as the hot water side. These valves are used to remove any excess water pressure left in the system. Go ahead and relieve that pressure on both sides before removing the attached hoses.

Once the hoses are removed, you will attach the additional hoses that should have been provided by the manufacturer. The theory here is to flush and drain 2.5 gallons of undiluted white vinegar through the system. This will help remove the limescale build up. Once completely flushed go ahead and seal everything back up.

Overall Assessment

As you can see, there are several considerations that must be made before one buys an on-demand water pump for cabin.

However, taking the time to carefully go over these considerations can help you choose the best water heater to suit your specific needs. Hot water might be a necessity, but it something that no one wants to go without. And, choosing the right water heater can help prevent this.

Weighing the above-mentioned considerations and taking the top three models into account can help put you in the right direction.
