Tankless Water Heaters: Pros and Cons

Tankless water heaters are a great innovation that has been available on the market for a few years now and offer many advantages over the traditional storage type heaters with very few drawbacks.

These devices look and function differently from traditional water heaters which work by heating water and storing it until it’s ready to be used. Tankless models however heat the water inline as it flows to the sink, bath or shower that is demanding it. Since it heats the water in this way, it is impossible to run out of hot water. This is the number one reason why our Markham plumbing customers make the switch to tankless heaters.

Another major advantage that comes with the switch to a tankless heater is the fact that you no long have to wait for hot water after turning on the faucet. This is because the water is heated internally in the machine as it flows through the pipes.

However due to its compact size and lack storage tank, one of the few drawbacks of this marvelous piece of equipment is a reduced flow rate when compared to a traditional storage type water heater. The average flow rate on a tankless model is generally between two and five gallons per minute with gas fired units offering a higher rate than their electric counterparts. Therefore more than one unit may need to be installed in larger homes to make up for this lower rate.

On the plus side, tankless heaters tend to have longer lifespans than those of the traditional storage variety leading to big savings for our Markham plumbing customers. Just imagine the benefits of a water heater lasting you as long as 20 years as opposed to storage models which can fail after as few as 10 years.

To make sure you get the maximum life out of your tankless heater there is only a minor amount of maintenance required and it can be easily handled by any certified Markham plumbing professional. This mostly involves simply flushing 3-5 gallons of vinegar or another light acid through the system periodically so as to remove any calcium deposits that may build up in the heater’s internal mechanisms.
