How high to raise water heater above floor?


re: "Can I just make one with 2x4 and plywood that's only 4" tall, basically just enough to be able to drain water off the drain tray? Or does the code require it be higher?"

I imagine you 'can' do that, but I wouldn't recommend that you do that.

I recommend you do the following:
1. Contact the Building & Code Enforcement office in your location to determine what (if any) codes regulate such a change to your water heater.

2. If they give you the go ahead & inform you of any regulations that you must follow, then ensure your water connection hoses are flexible enough to withstand the lift that you intend to make (you may need to replace rigid or semi-rigid connection piping with properly pressure & heat rated braided hoses. Also, double check your overflow piping to ensure that it will be adequate after the lift (this may require you to install a pipe extension or replace the down pipe so it isn't too high above the drain pan (which could cause scalding if...

Re: Question About Raising Gas Water Heater 18" Above Floor.

Don, you don't mention what size heater this is, or for what size family it will serve.

We have had to use 18" tall pans when there is no room to raise the heater. This satisfies our local inspectors provided the pan has a sealed door installed in it.

We use a butyl caulking compound to seal the door. This allows access to the burner and controls if needed. I don't like this method and its a last resort as far as I'm concerned.

I would do all I could do, including replacing the heater with another type in order to avoid the pan.

You can relocate the heater, enclose it in a closet with make up and combustion air piped in from attic or outside; you can go to a tankless heater as suggested; you can go to a small boiler type heater; you can go electric... The list goes on and on.

Water heating is a thermodynamic process that uses an energy source to heat water above its initial temperature. Typical domestic uses of hot water include cooking, cleaning, bathing, and space heating. In industry, hot water and water heated to steam have many uses.

Domestically, water is traditionally heated in vessels known as water heaters, kettles, cauldrons, pots, or coppers. These metal vessels that heat a batch of water do not produce a continual supply of heated water at a preset temperature. Rarely, hot water occurs naturally, usually from natural hot springs. The temperature varies based on the consumption rate, becoming cooler as flow increases.

Appliances that provide a continual supply of hot water are called water heaters, hot water heaters, hot water tanks, boilers, heat exchangers, geysers, or calorifiers. These names depend on region, and whether they heat potable or non-potable water, are in domestic or industrial use, and their energy source. In...

Radiant floor heating can be considered a better method of indoor climate control than more traditional systems as it’s a quiet and virtually invisible system. There are two types of floor heating to choose from when considering getting floor heating, which are electric and hydronic.

Electric heating is usually the best option for smaller spaces like a single room. This system is powered by electric cables or conductive plastic mats that are built into the floor.

There are many advantages to using electric floor heating. For one, the process to install is quite simple and can be perfect for remodeling projects, and the labour costs very little. The heating can also work on-demand or on a schedule in specific rooms to optimize thermal comfort.

Some disadvantages are that they use a lot of electricity, raising the energy bill, and it can be difficult to install in larger spaces.

Hydronic systems make use of hot water instead of electricity. This system is...

I will show you how to build a cheap and easy water heater to use for camping, hunting cabins, or anywhere that hot water isn't readily available. I have also include pictures of my finished product. I travel a lot in my motor home and don't like using LP Gas so I tinkered with some materials and came up with this. All in-home water heaters use a lot of energy but the one I built uses less than 1200 watts (10 amps). I wouldn't recommend using this in a house unless you modify the directions as standard houses use water pressure (town water or well). When I camp out, I take a 1500 watt power inverter and hook to my car battery to heat my water. I went to Wal-Mart and purchased a shower tent and used cpvc to run into tent and put a valve and a shower head on and it's ready to go.

On this step, you DO NOT have to take the reservoir off of the coffee maker. You do have to drill (2) 3/4'' holes in the back of the coffee maker to re-route the water lines and you have to take the...

One of the most vital issues in the winter is heating. Dozens and even hundreds of different solutions and methods for installing systems have already been developed. Someone continues to use the stove heating method due to the availability of fuel, others switched to solar collectors, since they live in an area where light days are enough. Most families have gas boilers and columns in their homes that provide heat to the frosts. Those who have hot water centrally, are wondering how to connect a water-heated floor from central heating.

The warm floor can hardly be called a novelty on the market. But the structure and approach to the installation of the warm floor continues to improve and from year to year it receives more and more new solutions that amaze with its efficiency and ease of installation. In total it is possible to distinguish two types of heated floors by power supply:

Each of them has its own nuances, except for the strengths. They are much easier to...

Floor Heating

What is hydronic radiant floor heating?

The Warm Floors Hydronic Radiant Floor Heating System consists of plastic tubing laid within the floor circulating warm water to different zones, warming the floor surface.

How does a hydronic radiant floor heating system work?
With a Warm Floors Hydronic Radiant Floor Heating System, warm water is circulated through PEX tubing to each room or zone. Once the water is passed to each zone, the water cools and returns to the heat source, is reheated and then re-circulated. Separate temperatures can be controlled using a multi-zone controller. Water can transfer energy more compact and efficiently than air. A Ѕ” tube can transport sufficient energy to heat an entire house. For details – please see the single zone controller.

Most homes have bedrooms on the second floor that need to stay warm and cozy in cool weather so everyone gets a good night's sleep. When your second floor isn't getting as much heat as you like, some simple methods may help direct more heat to the second floor. Heat tends to rise, often making it easier to heat the second floor than the ground floor.

Vents and Doors

Closing strategic vents in your home may help force more heat to your second floor. Close vents in any downstairs rooms that you don't use often or that have multiple vents; for example, a large living room may have three vents, but it gets enough heat to only need one. Closing vents helps push more heated air to the open vents, so make sure all your upstairs vents are wide open. Also, open all upstairs doors to help heated air flow into each room. When you close the vents in some seldom-used rooms downstairs, close the doors to those rooms to prevent losing heat from other rooms. Any doors that block...

A gas hot water heater troubleshooting guide is a guide that helps homeowners to deal with the most common problems related to pilot light, thermocouple, gas valve and gas related components. Find out what the most frequent causes, symptoms, and solutions are.

Before you perform any repair on the gas water heater keep in mind that leaking propane and natural gas can be dangerous. It is good to know that natural gas, when it is leaking tends to rise up while propane, as it is heavier than the surrounding air, collects at the floor level.

Gas hot water heater troubleshooting - Safety first

If you smell a leaking gas near the gas water heater, shut off the pilot light, close the main gas valve and DO NOT activate any electrical power switch, not even a light. Call a plumber or gas utility immediately, from the remote location (outside for example). This is a big problem where any spark is hazardous.

" I smell a gas" - you would say... but that doesn't mean...
