GEARLASSO DH002 is an all-in-one diesel parking heater listed for 12V/24V use, with an LCD display, remote control and claimed app control. Its advertised heat output and fuel-use figures may help compare it with your space and running needs, but they are listing claims rather than independently verified performance.

## At a glance

- An all-in-one diesel air heater presented for campervans, motorhomes, trucks, vans, boats, garages and workshops.
- The listing claims app, remote and LCD control, with adjustments for temperature, fuel-pump frequency and heating modes.
- A 5L tank and claimed fuel use of 0.15–0.45 L/h are provided for planning, but actual runtime depends on operating conditions.

## Pros

- Remote and app controls are both claimed, offering alternatives to the heater's display.
- The listing states a 5L tank and gives a fuel-consumption range, which can help buyers estimate diesel use.

## Cons

- Customer feedback reports mixed experiences with noise and installation, so buyers seeking quiet operation or a straightforward fitting should account for uncertainty.

## Before you buy

- The listing's claimed 8KW rating, 4,700–17,000 BTU output, 269 ft² \(25m²\) coverage, 5–10-minute warm-up and fuel-use figures are not independently verified. The listed dimensions of 1 x 1 x 1 cm alongside a weight of 9.82 kg appear inconsistent, and the AAA battery entry is not clearly reconciled with the heater's power and control details. Confirm relevant specifications and included items before purchase. Use the heater only with suitable exhaust venting. The listing claims external exhaust venting but does not establish safe installation for every setting.

## A good fit for

- Campervan, motorhome or vehicle owners seeking an all-in-one diesel heater with remote and claimed app control.
- Buyers comparing stated fuel use and tank capacity before choosing a heater for a workshop, garage or vehicle.

## Less suited to

- Buyers who need independently verified heating output, fuel consumption or area coverage.
- Anyone needing confirmed dimensions, a guaranteed noise level or assured installation simplicity.

## Customer feedback

Customer feedback is generally favourable about perceived quality, reliability and heat output, with reports of the heater working in a camper and helping make a barn usable in cold weather. Buyers also report mixed experiences with installation and noise, and some feedback criticises the instructions. These experiences provide useful context for a heater advertised with remote and app controls, but do not verify its claimed output or performance for a particular space.
- Positive themes: Customers describe the heater as good quality and effective, and some praise its heat output.
- Positive themes: Some customers say it was straightforward to install, while others report installation issues.
- Negative themes: Some customer feedback is critical of the instructions.
- Mixed feedback: Noise feedback is mixed, with some finding the heater quieter than expected and others describing it as noisy.

## Frequently asked questions

### Can this heater be used with a 12V or 24V supply?
The product title lists 12V/24V. Confirm compatibility with your vehicle's electrical system and the selected listing before buying.
### Does it support smartphone control?
The feature listing claims smartphone app control, alongside a remote and LCD display. App compatibility details are not supplied.
### How much diesel does it use?
The listing claims 0.15–0.45 L/h and a 5L tank. Treat these as manufacturer claims rather than a guaranteed runtime or independently measured consumption.
### Are the stated dimensions reliable?
The listing gives 1 x 1 x 1 cm and a weight of 9.82 kg. Those details appear inconsistent, so confirm the actual dimensions before planning installation.
