Pool Heater Installation in Miami

DG Pool Supply and Service installs pool heaters in Miami and Kendall, Florida — heat pumps and gas heaters, installed correctly, sized for your pool, and started up by people who do this work every day. If your pool is too cold to enjoy in the morning, too cold in winter, or your old heater has stopped heating altogether, we can help you choose the right replacement and install it without a long, complicated process.

Most Miami pools do not need a heater that fights freezing weather. They need a heater that warms the water reliably through the cooler months, holds a comfortable temperature for evening swims, and does it without a painful electric or gas bill. That is the job we size and install for, every time.

Pool heater installation installed from $3,500. Our featured offer is a Rheem CrossWind V 118,000 BTU heat pump, installed for $3,650. Message us on WhatsApp at 305-877-8960 or get a quote and we will confirm the exact price for your pool before any work starts.

Pool Heater Installation and Replacement in Miami and Kendall

We install new pool heaters and replace heaters that have reached the end of their life. A replacement is often the simplest job of all: we remove the old unit, check the plumbing and electrical or gas connections, fit the new heater, and test it so you can see it heating your pool before we leave.

Many of the heaters we replace in Miami are more than ten years old. They heat slowly, stop and start, trip breakers, leak, or cost more to run than they should. If you are repairing the same heater again and again, a new, efficient heat pump is usually the better use of your money — and you get a fresh manufacturer warranty with it.

We work across Miami and Kendall, including homes with screened enclosures, rooftop and ground-level equipment pads, and pools that were built before the current heater was added. We will tell you honestly if your pad, plumbing, or electrical service needs a change before installation, and what that change involves.

Heat Pump vs. Gas Heater: Which Is Right for a Miami Pool?

Most Miami homeowners choose a heat pump, and for good reason. A heat pump moves heat from the warm Miami air into your pool water instead of creating heat by burning fuel. In our climate that is efficient, steady, and well suited to keeping a pool at a comfortable temperature for most of the year. It heats more slowly than gas, so it is best when you want to keep the pool warm over days and weeks, not heat a cold pool in a few hours for a single evening.

A gas heater heats much faster and is a good choice if you use the pool occasionally and want hot water quickly, if you heat a spa, or if you already have a suitable gas line. Gas heaters cost more to run per hour in Miami, and they need a gas supply, proper venting, and the right clearances. Raypak gas heaters are available in our pool heater catalog, and we can talk through whether gas or a heat pump makes more sense for how you actually use your pool.

There is no single right answer for every pool. Pool size, sun and wind exposure, whether the pool is screened, how warm you like the water, and how often you swim all matter. We size the heater to your pool, not to a guess, and we explain the trade-off in plain language before you decide.

Heat and Chill: Warm in Winter, Cooler in Summer

Some Rheem heat pumps, including the CrossWind V, offer a Heat & Chill option. In heating mode the unit warms your pool. In chill mode it can cool the water when a Miami summer makes the pool feel more like a warm bath than a refreshing swim.

Heat & Chill is worth considering if your pool gets very warm in July and August, if you like a cooler pool for exercise, or if you want one unit that can handle both seasons. Ask us about it when you request your quote — it is an option on the right models, not something every pool needs.

How Pool Heater Installation Works: Three Simple Steps

Step 1 — Send a photo of your current heater label by WhatsApp. Send the photo to 305-877-8960 on WhatsApp. The label tells us the brand, model, BTU rating, and age of your heater, and a photo of the equipment pad shows us the plumbing and electrical connections. If you do not have a heater now, send a photo of the pad and tell us the size of your pool.

Step 2 — Get your exact quote. We review the photos, check the size and model that fits your pool, and give you an exact installed quote. You can also request a quote online. No vague estimate, no pressure to decide on the spot.

Step 3 — Install and start-up. We install the new heater, connect it, check for leaks, set the controls, and run it so you can see it heating. We show you how to set the temperature, how the timer and pump settings work with the heater, and what to check if it ever seems not to be heating.

What a Good Installation Includes

A heater is only as good as its installation. A unit that is too small will run all day and never reach temperature. Plumbing that is too tight will restrict flow and strain your pump. A heater without enough air around it will not heat efficiently. We check pool volume, flow, pad space and clearances, electrical supply, and controls before we recommend a size.

We also check that your pump and filter are in good working order, because a new heater cannot do its job if water is not moving through it properly. If we find a separate problem, we will tell you — we would rather fix it now than leave you with a new heater on a system that cannot support it.

Gas Line or Electric Requirements

Heat pumps run on electricity and need a suitable electrical circuit and breaker. Most homes already have what is needed, or need only a straightforward electrical connection. We will confirm the requirement for the model you choose and tell you if an electrician is needed.

Gas heaters need a gas line of the right size, a suitable gas meter and regulator where required, and proper venting and clearance. If you do not have gas at the equipment pad, adding it can be a separate job with its own cost. That is one reason many Miami homeowners choose a heat pump: no gas line, no venting, and lower running costs in our climate.

Do not guess at these requirements. Send us the photos, tell us what power and gas you have at the pad, and we will confirm what your installation needs before you buy anything.

Frequently Asked Questions

How long does pool heater installation take?

Usually the same day once we are on site. A straightforward replacement on a ready pad is normally completed in one visit. A new installation, a larger unit, or extra plumbing or electrical work can take longer, and we will tell you the expected time when we quote the job.

Do I need a gas line or extra electrical work?

It depends on the heater you choose. Heat pumps need a suitable electrical circuit. Gas heaters need a gas line, proper venting, and clearances. We check your existing connections from your photos and confirm what, if anything, needs to change before installation.

How long do heat pumps last in Miami?

With normal use and care, a quality heat pump in Miami commonly lasts many years. Its exact life depends on the model, how often it runs, water chemistry, and whether it is kept clean and protected. Heat pumps in Miami work in warm air for much of the year, which suits them well, but salt air, sun, and poor water balance can shorten the life of any pool equipment. We will give you simple care guidance at start-up.

What warranty do I get?

Warranty follows the manufacturer. The exact length and terms depend on the heater model you choose, and we will confirm them for that model before you buy. Keep your proof of purchase and follow the manufacturer's care guidance so the warranty stays valid.

Can you replace my old heater with a different brand?

Yes. We often replace an old gas or heat pump heater with a Rheem heat pump. We check the plumbing, electrical or gas connections, and the space on your pad, and adapt them where needed so the new unit fits and works properly.

Will a heat pump heat my spa too?

A heat pump can heat a spa, but it heats more slowly than gas. If you use a spa often and want it hot quickly, a gas heater or a larger heat pump may be a better choice. Tell us how you use the spa and we will size accordingly.
