If your family has changed, this might be the time to reassess your needs. This could mean a replacement that has the capacity to handle a bigger job. This is also a good time to catch up on what’s new in water heating technology.

Rising fuel costs have given everyone an increased awareness of the energy efficiency of home appliances. This can translate into sizable savings over the life of a water heater. For a gas tank model with average residential use this could mean 60 percent ER over a 12-15 year life, for a tankless model this could be 80-85 percent over 20 years. Electric models have an even higher rating.

There are a few other points we must consider before the plumber comes. In fact, with tankless water heaters a plumber may not be the right person to call. Many are not yet experienced in this technology. But I’m getting ahead of myself. First it’s necessary to determine three things:

1) Where you live geographically
2) How much you pay for electric and natural gas service
3) What is the gallons per minute usage during peak times

Here are the details for calculating the right tankless heater for your needs. Tankless water heaters operate on the principle of GPM (gallons per minute) and TR (temperature rise) for hot water output. GPM you can figure with estimates like a sink faucet: ¾ gpm, tub: 2-1/2gpm, shower: 1-½ gpm or clothes washer 2-½ gpm. Or you can take your own measurements. Temperature rise is also a number you can measure for yourself. From a manufacturer’s website, which plots out these two axes you will find the size heater they recommend for your needs.

Some residences have hot water tanks installed where there is space rather than for the most efficient use. If this problem has plagued you for too long, a residential tankless hot water heater can give you the opportunity to revisit this problem. Small, easy to mount tankless models can be placed almost anywhere there is wall space. Multiple tankless units can also be configured to maximize efficiency. You could, for instance, have the main gas tankless in the basement and a smaller electric in the kitchen or bedroom. There are many possibilities.

A residential tankless hot water heater is probably the best way to cover you family’s needs. If initial costs seem high when compared with a tank type try comparing the two over the life span of 12 years, which is how long a tank water heater is expected to last. Also keep in mind that natural gas prices have doubled in the past decade, climbing 25 percent in 2008 alone.
A tankless hot water heater is technology that should last 20 or more.
