The tank in the basement usually gives its warning quietly. Hot water runs out a few minutes sooner, the second shower of the morning turns cold, and then one day there is water on the floor. In Richmond, where plenty of houses still run a 40 or 50 gallon tank tucked into a crawl space or a hall closet, that moment is when most homeowners first think seriously about going tankless. A wall-mounted unit heats water only when a tap opens, frees up floor space, and typically lasts closer to 20 years than 10.
Tankless is also the kind of upgrade where installation quality decides whether you love it or regret it. Gas line sizing, venting, water hardness and recirculation all have to be right, and a unit sized for the wrong household will disappoint no matter how good the brand is. The five companies below all install and service tankless water heaters in the Richmond area, and each one publishes a real page describing that work. We ranked Foster Plumbing & Heating first because it pairs a licensed in-house plumbing department with three generations of Richmond history, hourly-paid technicians who are not chasing a commission, and a stated willingness to recommend a tank when a tank is the better answer.

Why They Stand Out
The Foster family has worked in the Richmond trades since 1946, and the company was incorporated in 1989. It is now in its third generation of family ownership, with roughly 98 employees and about 30 field technicians covering a service radius that runs from Petersburg to Ashland and New Kent out toward Louisa.
On the water heater side, the company is direct about the fact that tankless is not automatically the right call. Its plumbers walk through how the household actually uses hot water first. A large family at home all day, running laundry and back-to-back showers, is often better served by a properly sized tank. An empty nester couple showering in the evening and running the dishwasher twice a week is close to the ideal tankless candidate, and that is where the efficiency gains show up on the bill. The company installs both, and it says the tankless conversions have grown steadily as homeowners see the technology mature.
That advice is easier to trust because of how the field staff are paid. Technicians earn an hourly wage or a salary rather than commission, so there is no financial reason to push a homeowner toward the bigger ticket. Technicians are NATE-certified, the company is a Trane Comfort Specialist and BBB-accredited, and it holds a 4.9-star average across more than 800 Google reviews. Phones are answered by a person rather than a menu, and emergency service runs 24 hours a day, which matters when a water heater fails on a Sunday.
Having plumbing, HVAC and generator crews under one roof also changes what a visit looks like. The company trains its HVAC technicians to glance at the water heater while they are in the crawl space and flag corrosion or a failing anode before it becomes a flood, and a plumbing inspection, a heating tune-up and a generator service can be bundled into a single appointment instead of three.
Highlights:
- Tank or tankless, based on the household. Hot water usage is assessed before a recommendation, and the company installs both rather than steering every homeowner to the same product.
- No-commission technicians. Techs are paid hourly or on salary, and every repair and installation carries a one-year craftsmanship warranty.
- One team for plumbing, HVAC and generators. Multiple services can be handled in one visit, and maintenance agreements start at $79 for the first system.
- Training the next generation locally. A three-year apprenticeship registered with Virginia DPOR currently has nine apprentices, three in plumbing and six in HVAC, with classroom work through Associated Builders and Contractors and the schooling paid for by the company.

What to Look for in a Tankless Water Heater Company in Richmond, VA
- Ask how they size the unit. The right answer involves your household’s peak hot water demand and groundwater temperature, not the square footage of the house. Undersizing is the most common reason homeowners end up unhappy with tankless.
- Confirm the gas line and venting plan up front. Most gas tankless units need a larger gas supply line and new stainless venting. A quote that ignores both is a quote that will grow later.
- Ask whether they will also recommend a tank. A company willing to talk you out of tankless when your usage does not suit it is a company giving advice rather than making a sale.
- Check how technicians are paid. Hourly or salaried technicians have no incentive to upsell equipment you do not need.
- Get the workmanship warranty in writing. In Richmond, one year of craftsmanship coverage on the installation is a reasonable baseline and is separate from the manufacturer’s warranty on the unit itself.
FAQ: Tankless Water Heaters in Richmond, VA
How long does a tankless water heater last?
Most gas tankless units are rated for roughly 20 years, against 10 to 12 for a typical storage tank, provided they are flushed on schedule. Richmond area water is moderately hard in places, so annual descaling matters to reaching that lifespan.
Will a tankless unit really give endless hot water?
It will supply hot water continuously, but only up to its flow rate. A correctly sized unit handles two showers at once in most homes. Running a shower, a dishwasher and a washing machine at the same time can outrun a small unit, which is why sizing is the whole ballgame.
Is tankless worth it if I have a big family?
Not always. Households that use hot water heavily throughout the day often do better with a well-sized tank, or with a tankless unit sized generously enough to keep up. Smaller households and evening-heavy usage patterns see the clearest savings.
How much space does the switch free up?
A tankless unit mounts on the wall and is roughly the size of a carry-on suitcase, which usually reclaims a full closet floor or a corner of the crawl space or garage where the old tank sat.
Does a tankless install need a permit in Richmond?
Yes. Gas line changes and new venting require permits and inspection in the City of Richmond and the surrounding counties. A licensed plumbing contractor pulls those permits as part of the job.
The Bottom Line
Going tankless is one of the few home upgrades that pays back in space, efficiency and daily comfort at the same time, but only when the unit is sized and installed correctly for the way your household actually lives. Any of the five companies above can do the work. Foster Plumbing & Heating earns the top spot in Richmond for assessing hot water use before recommending a product, installing both tank and tankless rather than pushing one, paying technicians hourly instead of on commission, and backing the installation with a one-year craftsmanship warranty. For a family business that has been in Central Virginia’s trades since 1946 and is now training the next generation of licensed plumbers in its own apprenticeship program, that is a solid place to start the conversation.
