Oil Fired Water Heater Service Across Rhode Island

C.W. Cummings Plumbing provides repair, replacement, installation, and service guidance for oil fired water heaters across Rhode Island. If your home uses oil heat, our team can help you understand the available hot water options.

Understanding Oil Fired Water Heaters

Oil fired water heaters can heat large amounts of water quickly. A system's recovery rate helps describe how much water it can heat in a set amount of time.

Recovery rate tells you how many gallons of water the unit can raise by 100 degrees in one hour. The right water heater depends on your household's hot water use and existing equipment.

01

Recovery Rate and Household Demand

A smaller household may need less hot water during busy times than a larger household with several showers, appliances, or fixtures in use. C.W. Cummings Plumbing can help you understand the hot water needs of your home.

02

Direct and Indirect Oil Water Heating

Oil fired water heating systems generally fall into two categories: direct and indirect. A direct oil fired system heats domestic water with its own burner. An indirect system uses your home's boiler to heat domestic water.

03

When to Request Service

No hot water, water around the unit, changing water temperature, slow recovery, unusual sounds, or an older system that needs attention are all good reasons to request service.

Get Help With Your Indirect System

Indirect water heater systems can look different from one home to the next. If you are not sure which setup you have, request service and add a photo of the equipment. C.W. Cummings Plumbing can help you understand the system and plan the appropriate service.

Some installations need a tempering valve, also called an anti scald control, to help manage water temperature. Our team can review the existing setup during service.

Oil Fired Water Heater FAQs

An oil fired water heater uses an oil burner to heat the water stored in the tank. These systems are common in homes that use oil heat and can provide hot water for showers, sinks, laundry, and other daily needs.

A direct oil fired water heater heats domestic water with its own burner. An indirect system uses the home’s boiler to heat domestic water through a coil or heat exchanger. C.W. Cummings Plumbing can help identify the system in your home and explain the available options.

I had some PEX fittings corroding and leaking from a different plumbing company. I was referred to Cummings from my well company and saw the positive reviews so decided to try. I was extremely satisfied with the all aspects of the process from the front office/scheduling (Dee) to the plumbing service quality and cost. Mateo was prompt/on time, extremely knowledgeable, and thorough. While doing the repairs he inspected the rest of the plumbing and recommended a shut off valve improvement so if the tankless water heater goes down it could be isolated so the rest of the house could run. My expectations for the service, quality, and cost were all exceeded and I would highly recommend their services. Thank you Dee, Mateo, and Cumming's Plumbing! MikeT

Great service provided by CW Cummings. We had a problem with a toilet flange that needed to be replaced. Matteo did an excellent job on the repair and rebuilding the toilet itself. Very clean with attention to detail. He also performed a whole house inspection and made a couple of recommendations with a quote to do the work. There were not any pressing issues and there was no pressure to have this additional work done. Overall fantastic experience and will definitely be using them again in the future.

Ken was fantastic! He came out to troubleshoot a dishwasher backup issue, patiently tested the drainage and walked me through everything until we determined repiping was the solution. He gave me a fair, upfront price that included the service fee to come to Warwick and was able to complete the repair right then and there—no second appointment needed. He was knowledgeable, clean, polite, and genuinely took the time to listen and educate me. Highly recommend Ken and CW Cummings for honest, thorough, and professional plumbing work!

Highly recommended. Ken was polite and professional. He helped us make the right choices and was able to schedule us for a same day repair when our water heater quit unexpectedly. He also did a great job repairing our shower on a separate call. We will call CW Cummings for all our plumbing needs.
