Tankless Water Heater Tips

Here are tankless hot water heater tips to help you with your next purchase or installation. Tankless hot water heaters have a number of options to consider when selecting them. You must determine whether to go with an electric on-demand or gas heaters, the right size and more. If you choose a tankless hot water heater you can lower your utilities bill between 5-50% or even more.

A tankless hot water heater works by moving water through the system rather than keeping a storage tank full as a conventional hot water heater does and it never runs out of water. The tankless water heater provides an unlimited supply unless water heater’s ability to heat it flow is surpassed. Generally, this it’s not an issue unless you’re running the dishwasher, a shower, and the washing machine all at the same time. In this case, it may only provide lukewarm water because it cannot heat all of the water passing through it this quickly. Though if you have a modern tankless water heater and stagger the appliances by a few minutes there’s a good chance you won’t have a problem.

One of the most useful tankless hot water heater tips is knowing most tankless water heaters utilize gas powered burners which require venting and it’s common for them to require larger flues than traditional gas storage water heaters. There are units which don’t require venting such as Bosch and Rinnai though this may not be practical in extremely cold weather. Others have power vents which allow you to utilize a side wall to exhaust power vents.

Some tankless water heaters such as those made by Bosch are up to 80% efficient. Most have a pilot light while others use electronic ignition. And some don’t require a pilot light but are a bit more expensive but also more energy efficient. Sometimes it’s a tight space you must install your tankless water heater and sealed combustion models are compact models for this type of situation. And Rinnai tankless water heaters, in particular, have a cooling touch vent system you may want to look into.

Whereas traditional storage tank water heaters will deteriorate and break down over time as they store water which has a mineral build up, a heat exchanger in a tankless water heater warranty is usually five to twelve years.

The difference when choosing between types of hot water heaters is that tankless rely on flow where conventional units rely on capacity. So tankless water heaters may not run out of water like a traditional model but they still may not be able to heat water fast enough to serve multiple fixtures simultaneously. The flow rate is determined by the BTY (British Thermal Unit) which is the equivalent of the amount of energy it takes to raise one pound of water by one degree Fahrenheit. The flow rate is measured in Gallons Per Minute (GPM). So the higher the BTU rating the higher the flow rate. Flow rates can vary from 1.2 to 6 and in order to give you an idea the 1.2 GPM model would handle a single bathroom sink. A 2.6 GPM one shower. A 4 GPM perhaps one shower and a sink. And a 6 GPM two showers.

Why Plumber.ca?

There are several plumbers out there. Many have experience. So why choose us over everyone else? Here are a few reasons:

check  No Hourly Charges – Many customers do not see the advantages of having a plumber who does not work by the hour. A plumber who works on a fixed price has no reason to stick around after the job is finished to ensure he gets paid more. Even if the job takes more time than required, you still pay the same amount.

check  Upfront, Exact Pricing – Every job we do has a set price shown in our price book. We go through with you exactly what the scope of the work will be to fix your problem and the costs involved. You know before we start what the final price will be -no surprises!

check  Rapid Response Times – Our highly efficient dispatch team will make sure our local plumbers are at your location as soon as possible. Under regular conditions, our plumbing technicians will arrive at your location within 24-hours. Service calls can take longer than expected and specialty parts may need to be ordered, which may push the wait times longer so we communicate ongoing.

check  Priority Calls – Emergency calls are our highest priority. We know they can quickly become a serious situation. You can place a priority call to ensure you are the next customer to be serviced. The technician will be at your location within 24 hours. All priority calls require a credit card upon calling.

check  Local Plumbers – There is no sense in calling a plumbing service that is in another city. We have plumbers in all major city centers across the GTA that can respond to your emergency when you need it.

check  Fully Loaded Work Trucks – A fully inventoried truck is crucial so that your problem can not only be diagnosed quickly, but fixed quickly as well. Even if the job requires a specialty part, we can have it ordered within 24 hours.
