When hot water is a business requirement
Commercial Water Heater Service in Denver, CO
A restaurant without hot water closes. We handle high-capacity tanks, tankless banks, recirculation loops and multifamily systems across Denver.
- Restaurants, salons, gyms, multifamily
- 24/7 priority response
- Planned replacement and redundancy design
- Health-department temperature compliance
Commercial hot water is a different problem from residential. The volumes are larger, the consequences of failure are immediate and financial, and there are compliance requirements attached — a restaurant three-compartment sink and a dish machine have minimum temperature requirements that an inspector will check.
We work with Denver-area restaurants, coffee shops, salons and barbershops, fitness studios, medical and dental offices, small hotels, churches, laundromats and apartment buildings from four-plexes up.
What we service
- High-capacity commercial tanks — 75 to 120 gallons, atmospheric and power-vented, single and in banks.
- Commercial tankless racks — multiple linked units with common venting and cascade controls, which give both capacity and redundancy.
- Booster heaters for dish machines requiring 180°F final rinse.
- Recirculation systems — pumps, aquastats, balancing valves and mixing valves on long runs.
- Multifamily central plants — storage and recirculation for apartment buildings, plus per-unit heaters in condo conversions.
- Mixing and anti-scald valves — storing hot and delivering safe.
Designing for uptime, not just capacity
The single biggest mistake in commercial hot water is one large heater with no redundancy. When it fails, the business stops. Two smaller units piped in parallel, or a cascade of tankless modules, means a failure reduces capacity instead of eliminating it — and it lets us service one unit without shutting down the kitchen.
The second most common mistake is sizing off the old equipment instead of the actual demand. We calculate based on fixture units, dish machine specifications, peak service hours and recovery requirements. A brunch restaurant and a dinner-only restaurant with identical square footage have very different hot water profiles.
| Business type | Primary demand driver | Typical approach |
|---|---|---|
| Full-service restaurant | Dish machine, 3-comp sink, prep | Commercial tank plus a 180°F booster, or a tankless bank |
| Coffee shop / cafe | Sinks and cleaning, modest volume | Single commercial tank or two residential-grade tankless |
| Salon / barbershop | Simultaneous wash stations, long runs | Tank with recirculation and a mixing valve |
| Gym / fitness studio | Sharp shower peaks | Large storage plus high recovery |
| Apartment building | All-day demand, long branch runs | Central plant with recirculation and balancing |
| Medical / dental | Temperature consistency, compliance | Redundant units with mixing valves |
Compliance and temperature
Colorado's retail food establishment rules require specific temperatures at warewashing fixtures — hand sinks need a minimum supply temperature, manual warewashing sinks have their own requirement, and high-temperature dish machines require a hot final rinse, usually supplied by a booster heater. At the same time, public-facing lavatories need anti-scald protection. Storing hot and mixing down at the point of use satisfies both, and it is how we specify commercial systems.
We document delivered temperatures at commissioning so you have something to hand an inspector.
Service contracts and planned replacement
Commercial tanks work harder than residential ones and fail sooner — six to ten years is common, less in hard-water or high-use applications. Waiting for failure means an emergency shutdown at the worst possible moment. Our commercial customers get scheduled descaling and flushing, anode inspections, T&P and mixing valve testing, and a written condition report that tells you when to budget for replacement rather than discovering it on a Friday night.
We also schedule commercial replacements outside your operating hours — overnight and early morning installs are routine for us.
Frequently asked questions
Do you offer 24/7 service for commercial customers?
Yes, and commercial accounts get priority dispatch. For restaurants and multifamily properties we can usually be on site within a couple of hours across the Denver metro, and we schedule non-emergency work outside your operating hours.
How large a commercial water heater do I need?
It depends on peak-hour demand rather than square footage. We calculate from fixture units, dish machine specifications and your busiest service period. Restaurants frequently need a commercial tank plus a booster heater for the 180°F final rinse.
Can you install two units for redundancy?
Yes, and for most commercial applications we recommend it. Two parallel units or a cascaded tankless bank mean a single failure reduces capacity rather than closing you down, and it lets us service one while the other runs.
Do you work with property managers and HOAs?
Regularly. We handle multi-unit buildings, coordinate access with tenants, provide itemized invoicing per unit or per property, and can carry out condition surveys across a portfolio for capital planning.
What temperature does a commercial kitchen need?
Requirements differ by fixture: hand sinks, manual warewashing sinks and high-temperature dish machines each have their own minimum. We design around storing at a higher temperature and mixing down where scald protection is required, then document delivered temperatures at commissioning.
