Liquid to Vapor Propane Evaporators | HVAC Heating

Liquid to Vapor Propane Evaporators

Liquid to Vapor Propane Evaporators

These evaporators serve a large complex where natural gas is unavailable. The complex needed fuel for boilers for heating and domestic hot water so these evaporators were installed too along with two very large LP tanks to handle the heating needs of the complex. As liquid propane (LP) has a specific weight of .504 (where water is 1) and propane vapor has a specific gravity of 1.5 (where the air is 1) making propane vapor 1.5 times heavier than air. (more…)

Natural Gas Versus Propane | HVAC Heating Fuels

Natural Gas Versus Propane | HVAC Heating Fuels
Natural Gas Versus Propane | HVAC Heating Fuels - What is the best for you when choosing between either natural gas or propane? What is your heating system fuel supply? In some cases, you will not have a choice between the two. Having natural gas supplied to your home or business will require a natural gas pipeline near your home or business.

If there is a pipeline near your home and you do not have a meter, you can call the gas company. Most of the time, they will install the meter next to your home at no cost. However, it is always good to ask if they are going to charge you for installing a meter for use in your residence or business. (more…)

Standing Pilot Gas Valve Propane Heating | HVAC Heating

Standing Pilot Gas Valve Propane Heating | HVAC HeatingStanding Pilot Gas Valve Propane Heating | HVAC Heating - How It Works. The standing pilot gas furnace uses a standing pilot to light the main burners. Many gas-fired water heaters have a standing pilot ignition system. The standing pilot gas ignition system is often referred to as a safety pilot because it increases safety.

Safety of ensuring the main burners are lit. The standing pilot can be used on a natural gas ignition system or an LP ignition system. These heating ignition systems are older and are slowly being replaced by more modern and safer electronic ignition systems.

Gas Furnace Facts

Gas Furnace FactsGas Furnace Facts - Gas Furnaces are the most used types of the heating appliance for our homes and businesses and modern gas furnaces range in efficiency ratings from 79% to 98%. Gas furnaces can either use propane or natural gas for fuel. That largely depends on whether natural gas is available at the location of the appliance.

Propane is used in rural areas and in urban areas where the natural gas pipeline infrastructure is not available. Natural gas is delivered via pipeline, while propane is delivered via trucks and pumped into tanks. Tanks locations are on the premises near the gas furnace. The gas furnace that utilizes the propane for fuel needs a fuel supply. Therefore, the proximity of the tank.

Gas Furnace ComponentsGas Furnace Components | HVAC Heating Systems. Different types of gas furnaces are available for purchase today and the older models which were installed many years ago still in operation. The older models were typically atmospheric-type gas furnaces and used a lot of gas to produce heat, much of which went up the flue because efficiencies were low.

The standing pilot atmospheric type gas furnaces still exist today, but they are slowly going the way of the dinosaur as newer more efficient furnaces are replacing them. (more…)

Changing a Standing Pilot Boiler to Electronic Ignition – Conversion Upgrade

Changing a Standing Pilot Boiler to Electronic Ignition

The Honeywell Y8610U Intermittent Pilot Retrofit Kit

Changing a Standing Pilot Boiler to Electronic Ignition - Conversion Upgrade - How many times have you spent time in the cold trying to light a pilot light on a standing pilot gas system?

I am certain if you are a service technician, then the previous sentence can be qualified with “How many frustrating times.” You go on a service call and find the old standing pilot gas system. Whether it is a water heater, furnace, or boiler, and you find the thermocouple is bad. Or some other reason that is keeping the pilot light from staying lit.

You clean the pilot burner and replace the thermocouple and walla…………..it lights and stays lit. The magical standing pilot works again. There is another option for you and your customer. And while it is not recommended in every situation it can help eliminate those pesky repeat service calls.

Calls where the pilot continues to go out for whatever reason? The sudden ghostly draft is one of the big reasons. Honeywell produces an electronic ignition retrofit kit that is ideal for residential and light commercial gas furnace systems. Gas systems that are eligible for an upgrade from standing pilot to electronic ignition (covers BTU ratings up to 270,000).

Changing a Standing Pilot Boiler to Electronic Ignition | Conversion Upgrade

The Y8610U Intermittent Pilot Retrofit Kit from Honeywell comes complete. It comes with a gas valve (Natural Gas to Propane (LP)) conversion kit in the box), ignition control, electronic spark assembly with flame sensor, ignition wire, and wiring harness. A seasoned technician will find wiring this a snap. Out of the box the gas valve can be used with either ½” or ¾” pipe so this will work with little changes made to the gas pipe.

From Standing Pilot to Electronic Ignition - Changing a Standing Pilot Boiler to Electronic Ignition

I recently upgraded my boiler from a standing pilot to this electronic ignition control. It reminded me of all those standing pilot furnaces and boilers out there that have been changed to electronic ignition by me when I was working in the field. I had recently purchased a new – old house (1920) that has a steam boiler in the basement. All summer, I kept thinking about upgrading the boiler to electronic ignition from a standing pilot.

Especially after a nasty springtime encounter with lighting the pilot light that reminded me of all the frustrating experiences. Finally, fall arrived, and it was time to start up the old boiler so we can have some heat. That is when I ordered the Y8610U Intermittent Pilot Retrofit Kit.

Throwing the Switch - Changing a Standing Pilot Boiler to Electronic Ignition

The intermittent pilot retrofit kit arrived, and immediately, I took it down to the boiler to make the new introduction. About an hour and a half later, I threw the switch for the main power. The boiler and the new electronic ignition module came to life by sparking. I couldn’t see it, but I could hear it.

About a second or two of sparking and I heard the pilot fire. A second later, the main burner’s fired and the old boiler (approximately 30 years old) got a taste of modern technology. Another hour in the basement was taking care of the boiler and doing annual boiler maintenance, and I can feel comfortable. Comfortable with the reliable heat this winter and the colder days of fall and spring.

Installation Made Easy by Honeywell

The manifold side of the gas valve is a ½ inch, but the kit comes with a ¾ inch flange if the manifold side of the gas valve requires ¾ inch. The gas supply side of the gas valve is a ¾ inch, but Honeywell includes a ¾ inch to ½ inch reducer bushing.

That makes it possible to use the include gas valve for either ¾ inch pipe or ½ inch black iron pipe. The most difficult part of the installation for me is usually not the piping or even the wiring but getting the pilot burner in the correct position to light the main burners.

The pilot burner is usually installed in a tight space, and you have to get it exactly right, so the main gas burners light right away when the main valve in the gas valve opens to feed gas to the main burners. We do not want any “whoosh” main burner ignition.

That means the pilot light is too far away from the main burner. That allows gas build-up, which can be dangerous. Make sure you get the pilot light in the recommended position per the manufacturer’s recommendations or guidelines.

Installation Tips

A few installation tips and features include the control only needs to be supplied with 24 VAC – no line voltage needed – you tap into the 24-volt transformer that should be with the boiler. Make sure you wire through all the safeties, so the control loses power when one of the safeties trips.

When the controller loses power, the burner shuts down. Always follow all the instructions when installing anything. Good luck with any future upgrades you decide to make concerning this retrofit ignition control kit.

Natural Gas Properties and Furnace Heating Efficiency

Natural Gas Properties and Furnace Heating Efficiency

Natural Gas Regulators

Natural Gas Properties and Furnace Heating Efficiency - Natural Gas is a popular fuel used for heating systems in America and other countries. If we look at the properties of natural gas and the heating efficiency of natural gas furnaces we will see that natural gas furnaces lose efficiency because of what is contained in natural gas as it is delivered to your home for consumption by your natural gas furnace.

Natural gas in its raw form coming straight from the ground needs to be refined to remove impurities that should not be contained in natural gas. As you read below you will see that in the refining process moisture is removed from the natural gas however during the refining process some of the moisture in the natural gas remains and therefore this affects the efficiency of your natural gas furnace.
