The article presents the results of improving the currently used technology for installing heat pumps. A new technology for geothermal probes` installation by inclined cluster drilling using the UNB-3 drilling rig is proposed. The authors prove that the advantages and novelty of this technology are as follows: small installation dimensions; drilling is carried out from one place on a small site with a diameter of only 1.5 m; only 2-3 workers are needed to complete the task; arranging wells by this method is 40-43% cheaper than arranging vertical wells. The cost of cluster drilling using the UNB-3 drilling rig for an individual residential building is 35-43% lower than the cost of drilling vertical wells for the same building.
