Choosing A Water Heating System: Common Questions
So you aren’t sure if an instant water heater is right for you? Below are commonly asked questions with notes on which unit mates that specific need.
I want to spend as little as possible today.
While point units may be low sot, instant water heaters are more costly to purchase an install. Local rebates can change this, but if you need to keep costs low today and are looking for a quick fix for a broken boiler, you might want to simply replace your unit with a tank, though lifetime costs may be higher.
I don’t want to get burned by hot water from my shower.
Tankless hot water systems often include options to prevent scalding. This can be ideal for parents with young children and older individuals worried about being burned by spikes in water coming from a tank.
My shower won’t get hot, or it takes a long time to heat up.
This can be caused by either an undersized water heater or if the pipes are long or run through a cold space. In either case, a point instant water heater system can help to both heat faster and to a higher temperature.
We keep running out of hot water.
Boilers run out of water because the water in the tank is used. Once this happens, the heater is trying to heat the water as it is being used. A traditional water heater cannot do this effectively and so the water gets much colder. An instant water heater has no tank and so it can deliver as much hot water as you need anytime.
I want to be more environmental, how can I do that?
A high efficiency unit of either type is a great fist step to being environmentally friendly. Tankless units tend to be especially green because they are both highly efficient and only run when in use and then they turn back off.
My power keeps going out, will an instant water heater be a problem?
It can be. Gas units of both types will keep working, but electrical instant water heater units will not have any hot water when the power is out. In most cases this is not a common issue, but if you have regular power outages, particularly in a cold climate, you may want to consider a gas unit if either type to ensure that you have warm water.
I have heard that instant water heaters require more maintenance.
There is an ongoing debate about this. Instant water heaters should be cleaned periodically to remove calc and other buildup. This maintains maximum efficiency and there is much evidence that with maintenance an instant water heater can last up to 20 years, which is a very long time between replacements for any water heating system.
Do some instant water heater units deliver inconsistent temperatures?
None of them are designed to do so, but as with any product, some lower quality units can have this happen, much like a low cost traditional water heating system will run out of how water very quickly. As with most things, you need to look at specific products rather than
