11. A PROFESSIONAL UNDERSTANDS PROPER SIZING
Part of the professional’s job is to properly size the water heater. That includes calculating the demands from multiple bathrooms, dishwashers, clothes washers and any other points-of-use.
12. A PROFESSIONAL UNDERSTANDS THE IMPORTANCE OF PROPER VENTING
It is critical to vent the unit to the manufacturer's specifications. Improper vent size, total length or configuration can lead to a dangerous build-up of carbon monoxide inside the home.
13. INSTALLING THE PROPER T&P VALVE
The temperature and pressure relief valve opens to relieve pressure. Improper installation or the choice of an inadequate valve can cause damage to the water heater or a hazardous pressure build-up.

18. A SIMPLE WATER HEATER…ISN’T
With new industry-wide design changes like the Defender Safety System™, today’s water heaters are more complicated than ever. Proper installation and service require that water heater manufacturers provide training and education. This valuable knowledge is only available to a professional installer.
19. PROPER DRAINAGE IS A MUST
After several years of good service, a water heater could leak or expel water due to pressure build-up. This could cause damage to floor coverings and other items. A professional will install a drain pan and pipe it properly to a drain.
20. GETTING THE RIGHT GAS WATER HEATER FOR YOUR HOME
Gas valves are designed to handle a specific type of fuel. Some gas-fired water heaters are designed for certain types of homes. Making the wrong choice can be a serious hazard.
21. KNOWLEDGE OF ELECTRICITY AND ITS USES
Installation of electric water heaters requires knowledge of the properly rated wiring material as well as knowledge of the home's electrical capacity. An adequate electrical service is a requirement.
22. A PROFESSIONAL UNDERSTANDS THERMAL EXPANSION
Do you have an open or closed water system? Closed systems are subject to thermal expansion and pressure build-up. Open systems can become closed when check valves, water softeners or water
meters are added. A professional will add an expansion tank to avoid
23. PRESSURE BUILD-UP IS A SERIOUS MATTER
Even if your water heater tank doesn't rupture from thermal expansion, pressure inside the tank can cause a constriction of the flue tube. This, in turn, can cause a back up of combustion gases and carbon monoxide inside the home.

Dual-purpose models can be used for space heating and snow melting when properly connected to a hydronic piping system. A professional knows where to find these special models.

Even if your water heater is functioning adequately, maybe you're not getting as much hot water as you need. It may be time to upgrade. It's tough for a retailer or non-professional to advise you. A professional can give you guidance and explain your options.
27. GETTING A PROPER DIAGNOSIS OF THE PROBLEM
If your water heater looks fine but it just won't make hot water, a professional can diagnose what may be a simple problem. You may just need an inexpensive replacement part.
